Answer 1

Largest organelle
Controls the cell
Contains genetic material
has a cell membrane
nucleolus

Question 2

what does Regi stand for?

Answer 2

Respiration
Execration
Growth
irritability

Question 3

mitochondria?

Answer 3

Looks like sausage

location for aerobic respiration

Question 4

organelles?

Answer 4

organelles means small organs with specialised functions

Question 5

Plasma membrane?

Answer 5

It is a selective barrier (selective permeability ) controls what goes in and out of the cell and has two layers

Question 6

What is a zygote?

Answer 6

a single cell

Question 7

What is cytoplasm?

Answer 7

Cyto -cell
Plasm-Material
It is a semi fluid more like gel and flows slowly it is the pace where most chemical reactions happens it stores sugars such glycogen and melanin

Question 8

what is mitochondria?

Answer 8

Mitochondria is shaped like a sausage, It’s is the power house of the cell. It is used for aerobic respiration which where chemical energy is available in the cell

Question 9

What are ribosomes?

Answer 9

Ribosomes can be found in small clusters of the cytoplasm where they make proteins in he cell. They can also be found on the outer surface of the nuclear envelope and the rough endoplasmic material.

Question 10

What is a smooth and rough endoplasmic reticular?

Answer 10

The endoplasmic reticular is a extensive series of interconnecting membranous canals in the cytoplasm.

Smooth ER-It synthesis lipid and steroid hormones
Rough ER-studded ribosomes and the site of protein synthesis

Question 11

What is Golgi apparatus?

Answer 11

It is a series of flattened fluid sacs, stacked like pancakes it exports and synthesis protein

Question 12

What is lysosomes?

Answer 12

Lysosomes are small membranous vesicles that are pinched of the Golgi apparatus

Question 13

What are centrioles?

Answer 13

Every animal like cell has two organelles called centrioles. centrioles are small set of microtubes arranged in a specific way. They are there to help cells divide such as mitosis or meiosis

Question 14

Nuclear envelope?

Answer 14

A membrane similar to the plasma membrane but with tiny pores so that substances can pass between it and the cytoplasm surrounds the nucleus

Question 15

Nucleolus?

Answer 15

Within the nucleus roughly spherical structure manufactures and assembles the components of ribosomes

Question 16

Smooth endoplasmic reticulum?

Answer 16

Synthesis lipids and steroid hormones. Some of the lipids are used to replace and repair the plasma membrane of organelles

Question 17

Rough endoplasmic reticulum

Answer 17

Studded with ribosomes. The site of protein synthesis

Question 18

What is does Ribosomes Contains

Answer 18

Ribosomes contain tiny granules of ribonucleic acid(RNA)

Question 19

What are the basic functions of a cell

Answer 19

1) Respiration
2) Excretion
3) Growth
4) Irritability

Question 20

What does the plasma membrane consist of?

Answer 20

It consists of phospholipids with proteins and sugars embedded in them
