Bab 2 Struktur Dan Fungsi Jaringan Tumbuhan

The given characteristics of the tissue, such as continuous division, undifferentiated and unspecialized cells, and thin-walled cells with abundant protoplasm, are all indicative of meristematic tissue. Meristematic tissue is responsible for the growth and development of plants, as it continuously divides and produces new cells. This tissue is found in areas of active growth, such as the tips of roots and shoots. Therefore, the correct answer is jaringan meristem.

Meristem primer adalah jaringan tumbuhan yang terletak di ujung akar dan batang yang bertanggung jawab untuk pertumbuhan panjang tumbuhan. Meristem primer terdiri dari sel-sel aktif yang terus membelah diri untuk menghasilkan sel-sel baru yang akan membentuk jaringan-jaringan baru. Dengan adanya aktivitas meristem primer ini, tumbuhan dapat terus bertambah tinggi karena sel-sel baru yang terbentuk akan mendorong pertumbuhan panjang pada bagian akar dan batang tumbuhan.

Gutasi is the process of water droplets being released through the hydathodes on the leaves. This process occurs when the root pressure in the plant is higher than the atmospheric pressure, causing water to be forced out of the hydathodes. This is different from transpiration, which is the loss of water vapor through the stomata on the leaves. Gutasi is a mechanism for plants to release excess water and is often observed in the morning or during periods of high humidity.

Slereid adalah jaringan yang umumnya menyusun kulit biji. Jaringan ini terdiri dari sel-sel yang pendek dan berbentuk tidak teratur, dengan dinding sel yang tebal dan keras. Slereid berfungsi untuk memberikan perlindungan dan kekuatan pada biji, sehingga dapat melindungi biji dari kerusakan fisik dan serangan hama.

The correct answer is "felem kearah luar, dan feloderma ke arah dalam." This answer states that the cambium gabus will form felem (phloem) towards the outside and feloderma (cork cambium) towards the inside. This is accurate because cambium is responsible for the secondary growth of plants, and in woody plants like cork oak, it produces phloem towards the outer bark and cork cambium towards the inner bark.

Lapisan gabus bukan merupakan struktur primer pada batang tumbuhan dikotil. Struktur primer adalah struktur dasar yang terbentuk pada tahap awal perkembangan tumbuhan dan terdiri dari epidermis, korteks, silinder pusat, dan kambium pembuluh. Lapisan gabus, atau periderm, adalah lapisan pelindung yang terbentuk pada batang tumbuhan yang lebih tua sebagai respons terhadap perlindungan dan perlindungan dari lingkungan eksternal.

Meristem apikal adalah bagian yang berperan dalam pertumbuhan dan diferensiasi ujung batang, akar, dan cabang. Meristem apikal terletak di ujung batang dan akar, dan bertanggung jawab untuk pertumbuhan panjang pada tumbuhan. Meristem ini terus menerus membelah dan menghasilkan sel-sel baru yang kemudian akan mengalami diferensiasi menjadi berbagai jenis jaringan seperti xilem, floem, dan jaringan epidermis. Dengan demikian, meristem apikal memainkan peran penting dalam perkembangan dan pertumbuhan tumbuhan.

The given options are all modifications of the epidermal tissue, except for "Lapisan gabus" which translates to "cork layer". The cork layer is not a modification of the epidermis but rather a modification of the secondary tissue in plants, known as the periderm. The periderm, which includes the cork layer, is responsible for protecting the plant from mechanical damage, pathogens, and water loss. Therefore, "Lapisan gabus" is the correct answer as it is not a modification of the epidermis.

The correct answer is "Epidermis akar." The epidermis of the root functions as a protective layer and is responsible for the diffusion and osmosis processes. It helps in controlling the movement of water, minerals, and other substances into and out of the root.

Perisikel adalah bagian terluar dari silinder pusat akar yang merupakan tempat keluarnya akar cabang.

The correct answer is "Xilem dan floem primer, kambium vaskular, dan empulur." This is because the question is asking for the central cylinder in the primary structure of dicot stems, which consists of xylem and phloem, vascular cambium, and pith. The other options mentioned different components but not all of them were part of the central cylinder in dicot stems.

The given options describe the characteristics of the epidermis tissue. The options state that the epidermis tissue consists of tightly packed flat cells, there is no intercellular space, it functions as a place for exchange of substances, and its surface is coated with cuticle. However, the option "Semua selnya tidak berklorofil" (all of its cells do not contain chlorophyll) is incorrect because the epidermis tissue does not contain chlorophyll, as chlorophyll is primarily found in chloroplasts of plant cells.

Transpirasi adalah proses di mana tumbuhan mengeluarkan air melalui stomata pada daunnya. Proses ini membantu mengatur suhu tubuh tumbuhan dan juga membantu dalam pengangkutan air dan mineral dari dalam tanah ke seluruh bagian tumbuhan.

The given options are all types of permanent tissues except for promeristem. Promeristem refers to the primary meristem, which is a type of tissue responsible for the growth of plants. It is not considered a permanent tissue because it is actively dividing and generating new cells. The other options, such as parenchyma, epidermis, vascular, and supporting tissues, are all examples of permanent tissues that have completed their growth and are specialized for specific functions in the plant.

The correct answer is Prokambium. Prokambium is the primary meristem that gives rise to the primary xylem and phloem tissues in plants. It is responsible for the initial development and differentiation of these vascular tissues, which transport water, nutrients, and sugars throughout the plant. Prokambium is found in the apical meristem, the growing tip of the plant, and is involved in the primary growth of the plant.

The given characteristics of the tissue, such as being dead, lacking cytoplasm, and having a cell wall composed of lignin, are all typical features of xylem tissue. Xylem tissue is responsible for the transport of water and minerals from the roots to the rest of the plant. The dead cells in xylem tissue form long, hollow tubes that allow for efficient water movement. Therefore, based on the given characteristics, the correct answer is xylem.

The correct answer is meristem lateral. Meristem is a type of plant tissue that is responsible for growth and development. Meristem lateral specifically refers to the meristem tissue located at the sides of the plant, which is responsible for the growth of lateral branches and secondary growth. This tissue allows the plant to increase in width and produce new branches, contributing to its overall growth and development.

Meristem tissue is a group of young cells which actively divide. This tissue is responsible for the growth and development of plants. The cells in meristem tissue are undifferentiated, meaning they have not yet specialized into specific cell types. Due to their ability to continuously divide, meristem cells give rise to new cells that can differentiate into various types of plant tissues, such as leaves, stems, and roots. Therefore, the correct answer is "A group of young cells which actively divide."

Parenchyma is a type of plant tissue that can be found in almost every part of the plant. It is responsible for various functions such as storage, photosynthesis, and secretion. Parenchyma cells have thin cell walls and large central vacuoles, allowing them to store water and nutrients. They also have the ability to divide and differentiate, making them versatile for different plant functions. Therefore, it is correct to say that parenchyma is a tissue that can be found in almost every part of the plant.

The correct answer is "Akar merupakan modifikasi dari batang." This statement is incorrect because roots are not modifications of stems. Roots and stems are two distinct plant organs with different functions. Roots primarily function to anchor the plant in the ground and absorb water and nutrients, while stems provide structural support and transport water, nutrients, and sugars throughout the plant.
