Question 21

nucleus

Answer 21

he nucleus is the membrane-bound organelle that controls the activities of the cell and contains the cell’s genetic material (DNA).

Question 22

nuclear pore

Answer 22

Nuclear pores are openings in the nuclear envelope that allow substances such as mRNA and ribosomes to move between the nucleus and the cytoplasm

Question 23

mitochondria

Answer 23

Mitochondria are organelles that carry out respiration and produce energy in the form of ATP.

Question 24

chloroplast

Answer 24

contains chlorophyll synthesise food by the process of photosynthesis

Question 25

cell wall

Answer 25

The cell wall is a rigid, non-living structure outside the cell membrane that supports, protects, and gives shape to plant and bacterial cells.

Question 26

ribosomes

Answer 26

Ribosomes are small structures made of RNA and protein where protein synthesis occurs.

Question 27

vacoule

Answer 27

A vacuole is a membrane-bound sac used for storage; in plant cells it is large and filled with cell sap, helping maintain turgor.

Question 28

endoplasmic reticulum

Answer 28

The endoplasmic reticulum is a network of membranes involved in the transport of materials within the cell;

Question 29

rough endoplasmic reticulum

Answer 29

Rough ER has ribosomes and makes proteins.

smooth endoplasmic reticulum

Answer 30

Smooth ER makes lipids.

Question 31

golgi apparatus

Answer 31

The Golgi apparatus is a stack of membrane sacs that modifies, packages, and transports proteins and other substances in the cell.

Question 32

prokaryotic cells(no letters)

Answer 32

Prokaryotic cells are cells that do not have a nucleus or other membrane-bound organelles. Their DNA is found free in the cytoplasm. Bacteria are prokaryotic

Question 33

eukrayotic cell(letters)

Answer 33

Eukaryotic cells are cells that have a nucleus and membrane-bound organelles such as mitochondria and chloroplasts. Animals, plants, fungi, and protists are eukaryotic.
