CELL ORGANELLES

Question 1

What is Cell Organelles?

Answer 1

structure that has one or more specific jobs to perform in the cell

Question 2

what is the difference between prokaryotic and eukaryotic cells?

Answer 2

Prokaryotic - no nucleus no organelles unicellular
Eukaryotic- Has nucleus , has organelles, multicellular
they both have DNA, ribosomes, cytoplasm and cell membrane

Question 3

what are the three domains of life?

Answer 3

Eukaryota, Bacteria, Archea

Question 4

what are the example of prokaryotic cells

Answer 4

Bacteria and Archea

Question 5

It controls the entry and the exit of certain substances

Answer 5

Cell Membrane/Plasma Membrane

Question 6

helps to keep stability of the cell. It is the site where many vital biochemical reactions take place.

Answer 6

Cytoplasm

Question 7

controls all of the cells activities. Itcontains the cell’s genetic material.

Answer 7

Nucleus

Question 8

a bilayer membrane which protects the nucleus by surrounding and acts as a barrier between the cell nucleus and other organelles of the cell.

Answer 8

Nuclear Membrane

Question 8

inside the nucleus. It plays a vital role in the production of the cell’s ribosome.

Answer 8

Nucleolus

Question 8

made up of a number of flattened sacs called cisternae

Answer 8

Endoplasmic Reticulum

Question 9

protein synthesis

Answer 9

RER

Question 10

lipid synthesis

Answer 10

SER

Question 11

a stack of membrane-bound flattened sacs and are responsible for the modification of proteins.

Answer 11

Golgi apparatus

Question 12

define Mitochondria

Answer 12

are round double membrane-bound organelles responsible for aerobic respiration. Their inner membrane is folded inside to form cristae.

Question 13

It is made up of DNA and stored in the nucleus, which contains the instructions for traits and characteristics.

Answer 13

Chromosomes

Question 14

Vacuoles

Answer 14

membrane-bound cell organelle, sequester waste products
The term means “empty space”. They help in the storage and disposal of various substances. They can store food or other nutrients required by a cell to survive. They also store waste products and prevent the entire cell from contamination. The vacuoles in plant cells are larger than those in the animal cells.

Question 15

are small spherical organelles, protein synthesis

Answer 15

Ribosomes

Question 16

type of cell has these characteristics,: contains DNA but no nucleus, contains flagella, ribosomes, cytoplasm, and a cell membrane

Answer 16

Bacteria

Question 17

which organelles are involved in manufacturing substances needed by the cell

Answer 17

Ribosome, rough ER, smooth ER

Question 18

What kind of cell contains a nucleus, mitochondria and chloroplast?

Answer 18

Plant

Question 19

What is the outermost boundary of an animal cell?

Answer 19

Cell membrane
