Answer:
answer of question number 1
1).....The Cerebellum's Gran kiule Cell is the smallest cell in the human body that is between 4 micrometers to 4.5 micrometers long.
2)…The RBC 's size also found roughly 5 micrometers.
3)…Most scientists suggest that sperm is the smallest cell in terms of volume. ...
The largest cell is ovum in the human body.

answer of question number 2
The nucleoid is an irregularly shaped region within the prokaryotic cell that contains all or most of the genetic material. The chromosome of a prokaryote is circular, and its length is very large compared to the cell dimensions needing it to be compacted in order to fit.

answer of question number 3
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

answer of question number 4
Aerenchyma is a spongy tissue that forms spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root

answer of question number 6
Blood is considered a connective tissue because it has a matrix. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. The fluid portion of whole blood, its matrix, is commonly called plasma.

answer of question Number 7
SIMPLE PERMANENT TISSUE:
It is formed from a group of permanent cells which are structurally and functionally similar and perform a common function.
Simple permanent tissue is classified into Parenchyma, Collenchyma and Sclerenchyma.
COMPLEX PERMANENT TISSUE:
It is also called as compound tissue and is formed from different type of cells that perform a common function.
Complex permanent tissue is classified into Xylem and Phloem. These are conducting tissues.
XYLEM: It is a complex permanent tissue that performs the function of conduction of water and solutes from the roots to the top of the plant and is composed of four types of elements which are Tracheids, Vessels, Xylem fibres and Xylem parenchyma.
PHLOEM: It is a complex permanent tissue that performs the function of transporting organic food in plants and is composed of Sieve elements, Companion cells, Phloem fibres and Phloem parenchyma.
I think so it is correct

answer of question Number 8
lysosomes
Lytic Granules from NK Cells: The True Suicide Bags
Collectively, they are called lysosome-related organelles or secretory lysosomes, usually contain a number of lysosomal hydrolases and membrane proteins, and are characterized by low luminal pH

answer of question Number 9
Nervous tissue is made up of different types of nerve cells, all of which have an axon. An axon is the long stem-like part of the cell that sends actin potential signals to the next cell. ... Functions of the nervous system are sensory input, integration, control of muscles and glands, homeostasis, and mental activity.

answer of question Number 10
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
