Kuis SiSTEM Organisasi Kehidupan Makhluk Hidup Kelas 7

The smallest part of a living organism is a cell. Cells are the basic building blocks of life and are responsible for carrying out all the functions necessary for an organism to survive and reproduce. They are the smallest unit of life and are capable of independent existence. Cells can vary in size and shape depending on the organism, but they all have a similar structure and function.

The correct answer is B. jantung. The heart is responsible for pumping blood to the entire body. It receives oxygenated blood from the lungs and pumps it to the rest of the body through a network of blood vessels. The heart's pumping action ensures that oxygen and nutrients are delivered to all cells in the body, while also removing waste products. Without the heart's continuous pumping, the body would not receive the necessary oxygen and nutrients, leading to organ failure and eventually death.

Organisme yang hanya memiliki satu sel dinamakan organisme uniseluler.

The correct answer is A. membran sel. The given options are all components of a cell, but only the cell membrane is found in both animal and plant cells. The cell membrane is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell. The other options, such as kloroplas (chloroplast), plastida (plastid), and dinding sel (cell wall), are specific to plant cells and not found in animal cells. Therefore, the correct answer is A. membran sel.

The correct answer is B. mitokondria. Mitokondria is the organelle responsible for cellular respiration, which is the process of converting glucose into energy. It is often referred to as the "powerhouse" of the cell because it produces the majority of the cell's energy in the form of ATP. Mitokondria have their own DNA and are believed to have originated from ancient bacteria that formed a symbiotic relationship with eukaryotic cells.

The correct answer is D. epidermis. The epidermis is a tissue that covers the outer surface of plants and acts as a protective layer. It helps prevent water loss, protects against physical damage, and serves as a barrier against pathogens and pests.

The correct answer is C. sel - jaringan - organ - sistem organ - organisme. This is the correct sequence of organization in living organisms, starting from the smallest unit (cell) to the largest (organism). Cells are the basic building blocks of life, and they come together to form tissues (jaringan), which then combine to form organs. Organs work together to form organ systems, and all the organ systems together make up an organism.

The correct answer is B. jaringan syaraf, jaringan ikat, dan jaringan otot. This is because the organs of the eye, such as the retina and optic nerve, are composed of nerve tissue (jaringan syaraf) which is responsible for transmitting visual signals to the brain. The eye also contains connective tissue (jaringan ikat) which provides support and structure to the various components of the eye. Additionally, there are muscles (jaringan otot) attached to the eye that allow for movement and focusing.

The correct answer is C. kolenkim dan sklerenkim. Kolenkim and sklerenkim are both types of plant tissues that provide support and strength to the plant. Kolenkim is a type of ground tissue that is found in young and growing parts of the plant, while sklerenkim is a type of tissue that provides mechanical support to mature parts of the plant. Together, kolenkim and sklerenkim act as a reinforcement system for the plant, helping it to withstand external forces and maintain its structural integrity.

The Golgi apparatus is responsible for the synthesis, modification, and packaging of proteins. It receives proteins from the endoplasmic reticulum and modifies them by adding sugars and lipids. It then packages the proteins into vesicles, which are transported to their final destination within or outside the cell. Therefore, the Golgi apparatus plays a crucial role in protein synthesis.
