1

Non photosynthetic cells

________ found in roots, seeds, flower petals, and other locations may have organelles that are similar to chloroplasts but are specialized for storing pigments, starch, oils, or proteins.

New cards
2

secondary growth

In trees and other woody plants, ________ increases the width of roots and shoots.

New cards
3

apical meristems

All of the cells and tissues that are derived directly from ________ constitute the primary plant body.

New cards
4

Vacuoles

________ store various compounds, including wastes, and in some cases, they digest wastes, as do animal lysosomes.

New cards
5

Rain

________ is abundant enough in these areas to support a lush growth of herbaceous plants- seed plants at lack woody tissue- yet scarce enough to exclude trees and most shrubs.

New cards
6

Chloroplasts

________ are, all importantly, the site of photosynthesis.

New cards
7

aboveground portion

A(n) ________ called the shoot system harvests light and carbon dioxide from the atmosphere to produce sugars, while a belowground portion called the root system anchors the plant and takes in water and nutrients from the soil.

New cards
8

pneumatophores of mangroves

The ________ in the genus Avicennia are specialized lateral roots that function in gas exchange.

New cards
9

division of apical meristem

The ________ cells, and differentiation of those cells, is responsible for primary growth, which is common to all plants.

New cards
10

Apical meristems

________ are located near the tip of each root and shoot.

New cards
11

apical meristems

As cells in ________ divide, enlarge, and differentiate, root and shoot tips extend the plant body outward, allowing it to explore new space.

New cards
12

Rain is abundant enough in these areas to support a lush growth of herbaceous plants-seed plants at lack woody tissue

yet scarce enough to exclude trees and most shrubs

New cards
13

aboveground portion

the shoot system harvests light and carbon dioxide from the atmosphere to produce sugars

New cards
14

perennial

they live for many years

New cards
15

phenotypic plasticity

their form is changeable, depending on environmental conditions

New cards
16

adventitious

they develop from an unusual source, the shoot system instead of the root system

New cards
17

anchor roots

adventitious roots at grow from nodes in the shoot system

New cards
18

prop roots

adventitious roots that help brace individuals in windy weather

New cards
19

pneumatophores

specialized lateral roots that function in gas exchange

New cards
20

Chloroplasts

the site of photosynthesis

New cards
