Bio - plant lesson (ew) + plant info in general maybe

Question 1

vascular plant def

Answer 1

plant with a vascular tissue (distributes water and nutrients throughout plant, like the circulatory system)

Question 2

Three types of plant tissues + brief explanation

Answer 2

ground tissue - makes up most of the plant body, stores food and provides physical support
vascular tissue - trasnports water, minerals, sugars around the plant
dermal tissue - outer protective layer of the body of the plant

Question 3

meristematic tissue

Answer 3

like a stem cell, can become anything in the plant

Question 4

permanent tissue

Answer 4

differentiated, no longer actively dividing

Question 5

two kinds of vascular tissue

Answer 5

xylem - conducts water, is dead
phloem - conducts sugars and other organic compounds, alive

Question 6

walls of xylem tissue are made of cellulose. What substance strengthens them?

Answer 6

lignin

Question 7

xylem and phloem: one has content flowing up and down, one has content flowing only up. Which is which?

Answer 7

xylem: water travells up
Phloem: sugars and other organic compounds travel up and down

Question 8

Ground tissue

Answer 8

A strand of conductive vessels in the stems or leaves of a plant with xylem on the inside, phloem on the outside, supports the plant for active growth

Question 9

Three types of ground tissue and descriptions

Answer 9

parenchyma: storage + photosynthesis, found in thin-walled tissue
Sclerenchyma: found in rougher tissue such as tree bark
Collenchyma: found in support tissue w irregular walls

Question 10

four factors that affect the rate of transpiration

Answer 10

light, humidity, temperature, wind speed, air pressure, etc.

Question 11

compare root hairs to villi in the intestines

Answer 11

they both help to increase the rate of absorption of nutrients because their finger-like shape maximizes their surface area

Question 12

monocots vs dicots (5)

Answer 12

1. monocots have one cotyledon (like a leaf embryo) instead of two in the seed
2. monocts have fibrous roots instead of tap roots (think: grass is a monocot, a carrot is a dicot)
3. monocots have parallel leaf veins instead of net leaf veis
4. in the stems of monocots, vascular bundles are scattered instead of in a ring formation
5. monocot flowers are in three parts instead of in fours or fives.
