Cells

Question 1

Filtration

Answer 1

A passive process where water and small solutes move across a membrane due to pressure

Occurs in capillaries and kidneys

Small molecules pass through while larger molecules don’t

Helps exchange nutrients,waste and maintain homeostasis

Question 2

Endocytosis

Answer 2

The process where the cell engulfs substances from outside by folding the plasma membrane inward

Forms a vesicle to bring materials into the cell

Phagocytosis cell eating large particles

Pinocytosis cell drinking extra cellular fluid

Receptor mediated Endocytosis selective uptake of specific molecules

Question 3

Exocytosis

Answer 3

The cell releases substances by fusing a vesicle with the plasma membrane

Common for waste removal,hormone release,or protein secretion

Question 4

The impact of aging cells

Answer 4

Decreased regeneration meaning slower cell division and repair

And damage accumulation

Decline in cell communication affecting tissue repair

Mitochondrial dysfunction meaningweaker cells

Question 5

Definition of tissue

Answer 5

Groups of similar cells that work together to form a specific function in the body.

4 diffrent types of tissue.Epithelial tissue,connective tissue,muscle tissue,nervous tissue

Question 6

Epithelial tissue

Answer 6

Covers and lines body surface,cavities and organs. It serves like protection,absorption,secretion

Question 7

Connective tissue

Answer 7

Supports,binds and connects other tissue. Includes bone,blood,adipose fat tissue,and cartilage

Question 8

Muscle tissue

Answer 8

Responsive for movement

Question 9

Nervous system

Answer 9

Conducts electrical impulses and processes information
