Q

Spongy tissue

A

Spherical blob like shapes with large Vacuole space. These cells cover a lot of area to get leave a lot for air to allow for gas exchange and storage, for the ground cells and stomata to use.

Vascular tissue

A

Xylem and phloem. Transport system.

20
Q

Ground tissue

A

Supports stomata may also produce materials for the plant.

21
Q

Tissues

A

Made of cells of the same kind to do a job

22
Q

Organs

A

Group of tissues, that work together to perform a job.

23
Q

Root organs

A

Needed for absorption, anchoring, stability, storage transport and hormone production

24
Q

Herbaceous plant

A

Nonwoody plant, epidermidis is typically only one cell layer thick. Dermal tissue.

25
Q

Shoot meristen

A

Area of growth, hormone production axen,

26
Q

Root hair

A

Increases H2O absorption

27
Q

Phloem

A

Water travels in both directions the phloem is companion by companion, cell and source cell and on the bottom It also has a companion cell and I think so, I root cell.

28
Q

Passive

A

Requires no energy examples osmosis, diffusion

29
Q

Active

A

Requires energy

30
Q

Prokaryotic cells

A

Unicellular organisms, lack, membrane-bound, organelles for example, the nucleus mitochondria. Includes bacteria.

31
Q

eukaryotic cells

A

More complex can be multicellular, defining characteristics, membrane-bound organelles.

32
Q

Equilibrium

A

a state of balance between opposing action

33
Q

Phospholipid

A

Hydrophobic tail. Hydrophilic head. They are proteins embedded in or on the bilayer. This makes it look like a mosaic when observed from above the fluid mosaic model.

34
Q

Hypotonic

A

Water moves into the cell animals cells Will swell and or burst . In plants It will increase the turgor pressure.

35
Q

Isotonic

A

Water moves. Equally animal cells will stay the same.

36
Q

Hypertonic

A

Water moves out. The cell animal cells will shrivel. Plant cells dry out.

37
Q

Phototropism

A

The directional plant growth in response to light

38
Q

Gravitropism

A

Directional plant growth from the gravitational pull

39
Q

GFP

A

Green fluorescent protein. It is from the luminescent jellyfish. Close bright green when exposed to UV light, scientist, can I attach it to certain segments of genes to look for specific information.

40
