Explain cell structure in animals and plants?
The cell is defined as the structural and fundamental unit of life. Both plant and animal cells contain some of the similar organelles that help them to perform cellular activities.
Animal cell structure:
An animal cell is a eukaryotic cell that lacks a cell wall. It consists of a nucleus and other cellular organelles. The animal cell is irregularly shaped due to the absence of a cell wall. The organelles present in animal cells include cell membrane, cytoplasm, Golgi apparatus, mitochondria, nucleus, lysosomes, peroxisomes, ribosomes, microtubules, endoplasmic reticulum, centrioles, cilia, and flagella.
Cell membrane: It surrounds the cell’s cytoplasm, enclosing its contents. It is the semi-permeable membrane regulating the entry as well as the exit of specific molecules and is present within the cell wall.
Cytoplasm: It is a gel-like substance present within the cell.
Lysosomes: Animal cells consist of lysosomes containing enzymes that digest the cellular macromolecules.
Golgi apparatus: It is accountable for manufacturing, storing, and distributing cellular products. It consists of larger and fewer Golgi apparatus.
Endoplasmic reticulum: An extensive membrane network having both rough ER and smooth ER.
Mitochondria: It performs cellular respiration and thereby generates energy for the cell.
Ribosomes: They are accountable for protein assembly and are found either free or attached to the rough endoplasmic reticulum.
Nucleus: It is a membrane-bound structure containing the cell’s DNA, required for growth, metabolism, and cell division.
Peroxisomes: It consists of enzymes that detoxify alcohol, break down fats, and form bile acids.
Cilia and flagella: These are specialized microtubule groupings protruding from certain cells that aid in cellular locomotion.
