What is the main function of the cell membrane in an animal cell?

The main function of the cell membrane in an animal cell is to regulate the movement of substances in and out of the cell. It acts as a semi-permeable barrier, allowing essential molecules like nutrients to enter the cell while preventing harmful substances from entering and allowing waste products to exit the cell. Additionally, the cell membrane helps in maintaining the cell's shape and providing structural support.

What is the function of the nucleus in an animal cell?

The nucleus in an animal cell functions as the control center, housing the cell's genetic material in the form of DNA. It regulates gene expression, controls cell growth and division, and plays a crucial role in the overall functioning and maintenance of the cell. Additionally, the nucleus is responsible for synthesizing RNA and coordinating cellular activities to ensure proper cell function and development.

Which organelle is responsible for producing energy in an animal cell?

The organelle responsible for producing energy in an animal cell is the mitochondria. Mitochondria are known as the "powerhouses" of the cell because they generate adenosine triphosphate (ATP), which is the main energy source used by cells for various biological processes.

What is the function of the endoplasmic reticulum in an animal cell?

The endoplasmic reticulum in an animal cell serves as a site for protein and lipid synthesis, folding, and transport. It also plays a crucial role in the detoxification of drugs and harmful substances, calcium storage, and the production of membranes for the cell.

Which organelle helps in the synthesis and packaging of proteins in an animal cell?

The endoplasmic reticulum (ER) is the organelle that plays a crucial role in the synthesis and packaging of proteins in an animal cell. The rough endoplasmic reticulum, covered in ribosomes, is involved in protein synthesis, while the smooth endoplasmic reticulum assists in folding proteins and packaging them for transport within and out of the cell.

What is the function of the Golgi apparatus in an animal cell?

The Golgi apparatus in an animal cell functions as a central hub for processing, modifying, and sorting proteins and lipids that are synthesized within the cell. It is responsible for packaging these molecules into vesicles for transportation to their final destinations, both within the cell and to the cell membrane or outside the cell. In addition, the Golgi apparatus also plays a role in producing lysosomes, which are organelles that contain enzymes responsible for breaking down cellular waste and foreign particles.

Which organelle is responsible for breaking down waste materials in an animal cell?

The organelle responsible for breaking down waste materials in an animal cell is the lysosome. Lysosomes contain enzymes that break down cellular waste, old organelles, and foreign substances to be recycled or eliminated by the cell.

What is the function of the lysosomes in an animal cell?

The function of lysosomes in an animal cell is to break down waste materials, cellular debris, and foreign invaders (such as bacteria) through the process of digestion, recycling the components to be reused by the cell. Lysosomes contain digestive enzymes that help in these breakdown processes, playing a crucial role in maintaining cell health and overall functioning.

Which organelle helps in cell division in an animal cell?

The centrioles are organelles that help in cell division in animal cells by forming the spindle fibers that separate the chromosomes during mitosis.

What is the function of the cytoskeleton in an animal cell?

The cytoskeleton in an animal cell serves several functions, including providing structural support to maintain cell shape and integrity, facilitating cell movement and migration, enabling intracellular transport of organelles and vesicles, and playing a role in cell division by helping to organize and segregate chromosomes. It consists of three main types of protein filaments: microfilaments (actin filaments), intermediate filaments, and microtubules, each with specific functions and contributing to the overall organization and functioning of the cell.
