leaves

Question 1

any usually flattened green outgrowth from the stem of a vascular plant

Answer 1

leaves

function of leaves

Answer 2

to produce food for the plant by photosynthesis

kinds of leaves

Answer 3

monocot and dicot

Question 4

are elongated, slender with parallel veins

Answer 4

monocot

Question 5

possess “branching veins”

Answer 5

dicot leaves

Question 6

netted venation

Answer 6

dicot leaves

Question 7

parallel venation

Answer 7

monocot leaves

Question 8

veins run parallel to each other or run parallel to the midrib

Answer 8

parallel venation

Question 9

is singular and never divided into smaller leaflet units. it is always attached to a twig by its stem or the petiole

Answer 9

simple leaf

Question 10

has leaflets, which are attached to the middle vein and have their own stalks

Answer 10

compound leaf

Question 11

a bunch of single leaves, all attached to the main stem called a rochis, which in turn is attached to a twig

Answer 11

compound leaf

Question 12

types of compound leaves

Answer 12

• pinnately compound leaves
• bi-pinnately compound leaves
• tripinnately compound leaves
  -palmately compound leaves

Question 13

the term “pinnation” refers to the process in which multi-divided leaflets arise from both sides of the rachis

Answer 13

pinnately compound leaves

Question 14

rachis divisions on pinnately compound leaves in which leaflets sprout in pairs along the rachis without a single terminal leaflet

Answer 14

even-pinnately compound leaves

Question 15

there is a single terminal leaflet at the top of the structure rather than a terminal pair of leaflets
known as imparipinnate

Answer 15

odd-pinnately compound leaves

Question 16

(double compound) leaves are twice divided; the leaflets are arranged along a secondary vein, which is one of the several veins branching off the middle vein

Answer 16

bipinnately compound leaves

Question 17

leaves are thrice divided, the leaflets themselves are bipinnate in the arrangement

Answer 17

tripinnately compound leaves

Question 18

has its leaflets radiating outwards from the end of the petiole, like fingers of the palm of a hand

Answer 18

palmately compound leaves

Question 19

use to describe the arrangement of leaves arounf the stem

Answer 19

phyllotaxy

Question 20

types of phyllotaxy

Answer 20

• alternate phyllotaxy leaves
• opposite phyllotaxy leaves
• whorled phyllotaxy leaves

Question 21

is the most common type of leaf arrangement. the leaves are arranged in an alternate fashion. this means that each leaf will arise from a different node from the side

Answer 21

alternate phyllotaxy leaves

Question 22

a type of leaf arrangement in which a pair of leaves arise at each node opposite to each other

Answer 22

opposite phyllotaxy leaves

Question 23

is when two or more leaves develop at each node.
- each node has 3 or more leaves arising from them

Answer 23

whorled phyllotaxy leaves

Question 24

importance of phyllotaxy

Answer 24

it is important for efficient light capture, reduced shading, and optimal spacing between leaves. This arrangement maximizes a plant’s ability to photosynthesize, contributing to its overall growth and productivity.

Question 25

distinguish between a leafy branch and a compound leaf other than the presence of axillary bud

Answer 25

A leafy branch typically refers to a branch that bears individual, simple leaves along its length. Each leaf in a leafy branch is attached separately to the stem or twig. In contrast, a compound leaf consists of multiple leaflets attached to a common leaf stalk or rachis.

Question 26

types of modified leaves

Answer 26

- storage - support - protection - reproduction - attraction - additional photosynthesis - absorption

Question 27

are modifed to store water and nutrients for the plant

Answer 27

storage

Question 28

types of storage

Answer 28

- fleshy and thickened leaves - bulbs

Question 29

often reffered to as succulents. these plants are adopted to store water in their leaves and stems, allowing them to thrive in arid environments

Answer 29

fleshy and thickened leaves

Question 30

are extended leaf bases in some species, function as food storage that enable a plant to lie inactive when water is scarce

Answer 30

bulb

Question 31

are modified for climbing and support

Answer 31

support

Question 32

types of support

Answer 32

- tendrils - hooks - floaters - supporting leaf bases

Question 33

to protect plants from herbivores

Answer 33

protection

Question 34

types of protection

Answer 34

- motile leaves - leaves reduced to spine - spiny leaves

Question 35

allows plants to reproduce asexually

Answer 35

reproduction

Question 36

buds or plantlets grow at leaf margins, bases and apices

Answer 36

vegetative propagation

Question 37

attract pollinators

Answer 37

attraction

Question 38

types of attraction

Answer 38

colored bracts

Question 39

types of additional photosynthesis

Answer 39

- expanded leaflike petiole - expanded leaflike stipules

Question 40

absorbs nutrients from others aside photosynthesis

Answer 40

absorption

Question 41

types of absorption

Answer 41

- insect-trapping leaves - thin uncutinized epidermis

Question 42

uptake nutrients from captured prey

Answer 42

insect-trapping leaves

Question 43

importance of plant modification

Answer 43

Plant modification is crucial for the survival and success of plants in diverse environments. It includes adaptations in structures, reproductive strategies, and defense mechanisms, allowing plants to optimize resource use, enhance reproductive success, and thrive in challenging conditions.
