these cells are in the nervous system and function to process and
transmit information.

Answer 5

*Nerve Cells

Question 6

Also called Neurons

Answer 6

*Nerve Cells

Question 7

They are the core components of the brain, spinal cord and peripheral nerves. They
use chemical and electrical synapses to relay signals throughout the body.

Answer 7

*Nerve Cells

Question 8

Functions of this cells include secretion, absorption, protection, transcellular
transport, sensation detection, and selective permeability

Answer 8

*Epithelial cells:

Question 9

These cells secrete products through ducts, such as mucus, sweat, or digestive
enzymes.

Answer 9

*Exocrine cells

Question 10

These cells are similar to exocrine cells, but secrete their products directly into the
bloodstream instead of through a duct.

Answer 10

*Endocrine cells

Question 11

These cells are found throughout the body but are
concentrated in hormone-secreting glands such as the pituitary

Answer 11

Endocrine cells

Question 12

The main function of this blood cells is to collect oxygen in the
lungs and deliver it through the blood to the body tissues.

Answer 12

 Red blood cells (erythrocytes)

Question 13

They are produced in the bone marrow and
help the body to fight infectious disease and foreign objects in the immune system.

Answer 13

Various types of white blood cells (leukocytes)

Question 14

Cells that are found in the circulatory system, lymphatic system, spleen, and other body tissues.

Answer 14

(leukocytes).

Question 15

the smallest living units within our body, but play a big role in making our body function
properly.

Answer 15

Cells

Question 16

The boundary of the cell

Answer 16

plasma membrane

Question 17

separates internal metabolic
events from the external environment and controls the movement of materials into and out of the cell.

Answer 17

Cell Membranes

Question 18

These are the molecules that are scattered throughout the flexible phospholipid membrane.

Answer 18

Protein and Cholesterol

Question 19

This proteins attach loosely to the inner or outer surface of the plasma membrane.

Answer 19

Peripheral proteins

Question 20

This proteins
lie across the membrane, extending from inside to outside.

Answer 20

Integral proteins

Question 21

Proteins that provide passageways through the membranes for certain
hydrophilic or water-soluble substances such as polar and charged molecules.

Answer 21

*Channel proteins

Question 22

Proteins that spend energy (ATP) to transfer materials across the membrane.

Answer 22

Transport proteins

Question 23

When energy is used to provide passageway for materials, the process is called?

Answer 23

active transport

Question 24

In channel proteins, No energy is used
during transport, hence this type of movement is called?

Answer 24

facilitated diffusion

Question 25

Proteins that distinguish the identity of neighboring cells. These proteins
have oligosaccharide or short polysaccharide chains extending out from their cell surface.

Answer 25

Recognition proteins

Question 26

Proteins that attach cells to neighboring cells or provide anchors for the
internal filaments and tubules that give stability to the cell
