Tissues and Organs of Animal and Plant Bodies

Question 1

What are the 4 main tissue types?

Answer 1

Connective, Nervous, Muscle, Epithelial

Question 2

Structure v.s Function

Answer 2

Structure: Appearance, composition, absolute and relative location
Function: Process, job

Question 3

Epithelial Tissue

Answer 3

Layers of tightly packed cells that line the surfaces of the body, organs, and sacs.

Protection, Absorption, Produce secretion (glands) when lines sacs.

Question 4

Connective Tissue: Structure

Answer 4

Cells arranged in an extracellular matrix (outside the cells) that hold other types of tissues together in organs

Question 5

Connective Tissue: Functions

Answer 5

Protects, supports, binds tissues, stores energy (fats) provides immunity

Question 6

What are the 4 types of Connective tissues?

Answer 6

Blood, loose, bone/cartilage, dense

Question 7

Connective Tissue: Blood

Answer 7

Liquid matrix; transports material and immunity components throughout the body

Question 8

Connective Tissue: Loose

Answer 8

Jelly-like; acts as cushioning and filler between organs
- collagen, adipose (fats)

Question 9

Connective Tissue: Bone/Cartilage

Answer 9

Solid; rigid with some flexibility; provides protection, structure, and support

Question 10

Connective Tissue: Dense

Answer 10

Firm; binds tissues together and provides support
- tendons, ligaments

Question 11

Nervous Tissue: Structure

Answer 11

Extensions to other cells to receive and deliver electrochemical signals and receptors for receiving sensory info

Question 12

Nervous Tissue: Functions (3)

Answer 12

• Respond to specific types of stimuli and sends info to the CNS
• Carry nerve impulses from the CNS to glands or muscles to carry out actions
• Integrate sensory info and known info and decide how to respond, and store that info in networks

Question 13

Muscle Tissue: Structure

Answer 13

Long cells with specialized proteins for contraction

Question 14

Muscle Tissue: Functions

Answer 14

Cause movement of organs, material within organs, or the whole body; attached to bones, in the heart, and lining the tubes of the body

Question 15

Contraction

Answer 15

The shortening of cells by up to 70% when it receives signal form neurons

Question 16

Microbiome

Answer 16

community of bacteria, protists, and fungi found on and in your body

Question 17

Plants vascular system

Answer 17

S: Thin tubes throughout root and shoot system
F:
xylem: dead cells that transport water and dissolved minerals from roots to leaves
phloem: Living cells that transport photosynthate from leaves to rest of the plant (2-way)
