Cells

Question 1

Cell membrane

Answer 1

is the outer covering of a cell within which all other cell components, such as the cytoplasm and nucleus, are enclosed. Itreferred to as the plasma
membrane and it is present in all cells.

Question 2

Cell wall

Answer 2

the most prominent part of the plant’s cell structure. It is made up of
cellulose, hemicellulose and pectin.

Question 3

Cytoplasm

Answer 3

a thick, clear, jelly-like substance present inside the cell membrane. Most of the chemical reactions within a cell take place in this cytoplasm

Question 4

Nucleus

Answer 4

is a spherical-shaped organelle that is present in every eukaryotic cell

Question 5

Nucleolus

Answer 5

is the site of ribosome synthesis. Also, it is involved in controlling cellular
activities and cellular reproduction

Question 6

Nuclear membrane

Answer 6

protects the nucleus by forming a boundary between the
nucleus and other cell organelles.

Question 7

Chromosomes

Answer 7

play a crucial
role in transferring hereditary informations across generations and determining the sex
of an individual

Question 8

Ribosome

Answer 8

are the cellular structures responsible for protein synthesis

Question 9

ER

Answer 9

is a network of internal membranes..

Question 10

Rough er

Answer 10

It is a series of connected flattened sacs having several ribosomes on its outer surface.

Question 11

Smooth er

Answer 11

The smooth endoplasmic reticulum has a tubular form.

Question 12

Golgi apparatus

Answer 12

Sorting, tagging, packaging, and distributing lipids and proteins takes place

Question 13

Mitochondria

Answer 13

Is the powerhouse of the cell

Question 14

Peroxisomes

Answer 14

Are small, round organelles enclosed by single membranes.

Question 15

Vesicles and Vacuoles

Answer 15

are membrane-bound sacs that function in storage and transport

Question 16

Lysosome

Answer 16

are the cell’s “garbage disposal

Question 17

Chloroplast

Answer 17

are plant cell organelles that carry out photosynthesis

Question 18

The central vacuoles

Answer 18

plays a key role in regulating the cell’s concentration of water in changing environmental conditions.

Question 19

Endomembrane system

Answer 19

is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.

Question 20

Microfilaments

Answer 20

are the narrowest.

Question 21

Intermediate tubules

Answer 21

have no role in cell movement. Their function is purely structural

Question 22

Microtubules

Answer 22

As their name implies, microtubules are small hollow tubes.

Question 23

Flagella

Answer 23

are long, hair-like structures that extend from the plasma membrane and enable an entire cell to move

Question 24

Cilia

Answer 24

They are short, hair-like structures that move entire cells
