Draw a labelled diagram animal cell Explain the function of control room of cell
Answers
Explanation:
Animal cells are generally smaller than plant cells. Another defining characteristic is its irregular shape. This is due to the absence of a cell wall. But animal cells share other cellular organelles with plant cells as both have evolved from eukaryotic cells.
A typical animal cell comprises the following cell organelles:
Cell Membrane
A thin semipermeable membrane layer of protein and fats surrounding the cell. Its primary role is to protect the cell from its surrounding. Also, it controls the entry and exit of nutrients and other microscopic entities into the cell.
Nuclear Membrane
It is a double-membrane structure that surrounds the nucleus. It is also referred to as the nuclear envelope.
Nucleus
It is an organelle that contains several other sub-organelles such as nucleolus, nucleosomes and chromatins. It also contains DNA and other genetic materials.
Centrosome
It is a small organelle found near to the nucleus which has a thick centre with radiating tubules. The centrosomes are where microtubules are produced.
Lysosome (Cell Vesicles)
They are round organelle surrounded by a membrane comprising of digestive enzymes which help in digestion, excretion and in the cell renewal process.
Cytoplasm
A jelly-like material which contains all the cell organelles, enclosed within the cell membrane. The substance found within the cell nucleus, contained by the nuclear membrane is called the nucleoplasm.
Golgi Apparatus
A flat, smooth layered, sac-like organelle which is located near the nucleus and involved in manufacturing, storing, packing and transporting the particles throughout the cell.

Mitochondrion
They are spherical or rod-shaped organelles with a double membrane. They are the powerhouse of a cell as they play an important role in releasing energy.
Ribosome
They are small organelles made up of RNA-rich cytoplasmic granules and they are the sites of protein synthesis.
Endoplasmic Reticulum (ER)
This cellular organelle is composed of a thin, winding network of membranous sacs originating from the nucleus.
Vacuole
A membrane-bound organelle present inside a cell involved in maintaining shape and storing water, food, wastes, etc.
Nucleopore
They are tiny holes present in the nuclear membrane which are involved in the movement of nucleic acids and proteins within the cell.
Animal Cell Types
There are numerous types of animal cells, each designed to serve specific functions. The most common types of animal cells are:
Skin Cells
Melanocytes, keratinocytes, Merkel cells and Langerhans cells
Muscle Cells
Myocyte, Myosatellite cells, Tendon cells, Cardiac muscle cells
Blood Cells
Leukocytes, erythrocytes, platelet
Nerve Cells
Schwann cell, glial cells etc
Fat Cells
Adipocytes
Mark me as a brainlist thankyou....
Explanation:
NUCLEUS IS CALLED CONTROL CENTRE OF THE CELL BECAUSE IT PERFORMS TWO MAIN PRINCIPAL FUNCTIONS: ... Controls cellular activities through directing synthesis of particular proteins and enzymes.
hope it helps u dear❤️❤️❤️
mark me as brainliest ❤️❤️❤️❤️
