Epidermis.
26
Multiple Choice: Which of the following is a characteristic of woody stems? A) Flexibility B) Hardness C) Softness D) All of the above
B) Hardness.
27
What type of leaf arrangement has leaves growing directly across from each other on the stem?
Opposite.
28
What are the three main characteristics of plants?
Multicellular, autotrophic, sessile ## Footnote These characteristics define plants as living organisms that produce their own food and do not move from place to place.
29
What are the two reproduction patterns exhibited by plants?
Sexual and asexual reproduction ## Footnote Plants can reproduce either by producing seeds (sexual) or by other means such as cuttings or runners (asexual).
30
How are higher plants categorized based on their reproductive system?
Non-flowering (gymnosperms) and flowering (angiosperms) plants ## Footnote This classification is based on the presence or absence of flowers and the way seeds are produced.
31
What distinguishes gymnosperms from angiosperms?
Gymnosperms have cones and naked seeds; angiosperms have flowers and seeds within a fruit ## Footnote This distinction is crucial for understanding plant reproduction and classification.
32
What are the main components of a typical angiosperm's shoot system?
Stem, branches, leaves, buds, and flowers ## Footnote These components are essential for photosynthesis, reproduction, and nutrient transport.
33
What does the root system of a plant typically include?
Primary or tap root, lateral roots, and root hairs ## Footnote The root system is responsible for anchoring the plant and absorbing water and minerals.
34
What layers make up the internal structure of a leaf?
Epidermis (upper and lower), palisade mesophyll, and vascular bundles ## Footnote Each layer has specific functions such as protecting the leaf, photosynthesis, and nutrient transport.
35
What is the function of stomata in a leaf?
Allow gas exchange and minimize water loss ## Footnote Stomata are small openings that facilitate the intake of carbon dioxide and the release of oxygen.
36
What is the process of photosynthesis?
Conversion of light energy into chemical energy, producing carbohydrates and oxygen ## Footnote This process is essential for plant growth and energy supply.
37
How is water and minerals transported in plants?
Through vascular bundles, specifically xylem ## Footnote Xylem transports water and minerals from the roots to other parts of the plant.
38
What is the role of phloem in plants?
Translocates food (organic matter) ## Footnote Phloem is responsible for transporting the products of photosynthesis throughout the plant.
39
What types of transport occur in plants?
Passive and active transport ## Footnote Passive transport includes diffusion and osmosis, while active transport requires energy.
40
What is tropism in plants?
A unidirectional response to a stimulus ## Footnote Tropism can manifest as positive (towards) or negative (away) responses.
41
What are the types of tropism, and what stimuli do they respond to?
* Phototropism (light) * Hydrotropism (water) * Geotropism (gravity) ## Footnote These responses help plants adapt to their environment.
42
Which part of the plant is positively phototropic?
The shoot ## Footnote The shoot grows towards light, enhancing photosynthesis.
43
What is the significance of medicinal plants?
They play a vital role in treating diseases and fighting infections ## Footnote Many traditional and modern medicines are derived from plant sources.
44
What is the primary function of leaves in plants?
Photosynthesis

To prevent water loss
59
Fill in the blank: The air spaces in the spongy mesophyll facilitate __________ exchange.
gas
60

False
63
What is a leaf's vein primarily made up of?
Vascular bundles containing xylem and phloem
64
Fill in the blank: The __________ layer of the leaf helps in reducing water loss and provides protection.
epidermal
65
What is the significance of leaf arrangement on a plant?
To maximize light exposure for photosynthesis
66
What is the main pigment found in chloroplasts?
Chlorophyll
67

B) Chlorophyll
68
True or False: Leaves can vary significantly in shape and size depending on the plant species.
True
69
What is the term for the process by which plants lose water vapor through stomata?
Transpiration
70
Fill in the blank: The __________ tissue in leaves is crucial for nutrient transport.
