2.

What organelle is represented by letter E?

Vacuole
Mitochondria
Golgi Apparatus
Chloroplast

Correct Answer

A. Chloroplast

Explanation

The correct answer is Chloroplast. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They contain chlorophyll, a pigment that absorbs sunlight and converts it into energy. The letter E in the diagram most likely represents the chloroplast because it is typically depicted as a round or oval-shaped structure with internal membranes called thylakoids.

3.

What organelle does arrow F represent?

Chloroplast
Mitochondria
Nucleus
Golgi apparatus

Correct Answer

A. Mitochondria

Explanation

Arrow F represents mitochondria. Mitochondria are double-membraned organelles found in eukaryotic cells that are responsible for producing energy in the form of ATP through cellular respiration. They have their own DNA and can replicate independently. The presence of arrow F indicates that the organelle being referred to is involved in energy production, which is a characteristic of mitochondria. Chloroplasts, on the other hand, are responsible for photosynthesis, the nucleus is involved in genetic material storage and regulation, and the Golgi apparatus is involved in protein modification and sorting.

4.

What does arrow G represent?

Endoplasmic Reticulum
Chloroplast
Golgi Apparatus
Vacuole

Correct Answer

A. Golgi Apparatus

Explanation

Arrow G represents the Golgi Apparatus. The Golgi Apparatus is an organelle found in eukaryotic cells that is responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It receives proteins and lipids from the endoplasmic reticulum and modifies them by adding sugars, lipids, or phosphate groups. The Golgi Apparatus then packages these modified molecules into vesicles and sends them to various parts of the cell or to the cell membrane for secretion.

5.

What does H represent?

Endoplasmic Reticulum
Golgi Apparatus
Mitochondria
Vacuole

Correct Answer

A. Vacuole

Explanation

H represents Vacuole. Vacuoles are membrane-bound organelles found in the cells of plants, fungi, and some protists. They are responsible for storing various substances such as water, ions, nutrients, and waste products. Vacuoles also play a role in maintaining cell turgor pressure, regulating pH levels, and storing pigments in plants.

6.

Which of the following is a Plant Cell?

Option 1
Option 2
Option 3
Option 4

Correct Answer

A. Option 1

Explanation

Plant cells are distinct from animal cells due to the presence of a rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole that maintains turgor pressure. These unique structures enable plant cells to provide structural support, produce energy through photosynthesis, and store essential nutrients, making them crucial for the plant's growth, development, and overall function.

7.

What cell organelle is represented by arrow A?

Cell Membrane
Cell Wall
Nucleus
Cytoplasm

Correct Answer

A. Cell Wall

Explanation

Remember, a plant cell has a Cell Wall on the outside that is rigid and square shaped

8.

What organelle is represented by arrow C?

Golgi Apparatus
Endoplasmic Reticulum
Nucleus
Chloroplast

Correct Answer

A. Nucleus

Explanation

Arrow C represents the nucleus. The nucleus is a membrane-bound organelle found in eukaryotic cells. It contains the cell's genetic material, which is organized into chromosomes. The nucleus controls the cell's activities and is responsible for storing and transmitting genetic information. It is typically located near the center of the cell and is surrounded by a double membrane called the nuclear envelope.

9.

Which part of the plant cell is responsible for maintaining turgor pressure?

Mitochondria
Ribosomes
Central Vacuole
Nucleus

Correct Answer

A. Central Vacuole

Explanation

The cell wall is a distinctive feature of plant cells that is not found in animal cells. It is a rigid, protective layer made primarily of cellulose, which gives the cell its shape and structural support. The cell wall allows plants to stand upright and protects them from mechanical stress and pathogens. In contrast, animal cells have only a flexible plasma membrane and lack this rigid outer structure. The presence of the cell wall also facilitates the formation of structured tissues in plants, such as leaves and stems, which is not possible in animal cells due to their lack of a cell wall.

10.

Which organelle is responsible for the storage of starch, oils, and proteins in plant cells?

Leucoplasts
Mitochondria
Chloroplasts
Ribosomes

Correct Answer

A. Leucoplasts

Explanation

Leucoplasts are a type of plastid found in non-photosynthetic tissues of plants, such as roots, tubers, and seeds. They are colorless and primarily involved in the storage of essential nutrients like starch, oils, and proteins. These stored compounds serve as energy reserves for the plant, supporting growth, development, and reproduction. Leucoplasts are especially important in plants that store large amounts of starch, such as potatoes and other root vegetables.
