Trees play a significant role in ____________________
-
Reducing erosion
-
Moderating the climate
-
None of the above
-
All of the above
Correct Answer
A. Reducing erosionExplanation
Trees play a significant role in reducing erosion. The roots of trees help to hold the soil together, preventing it from being washed away by water or blown away by wind. The canopy of trees also acts as a barrier, reducing the impact of rainfall on the soil surface. This helps to prevent soil erosion and the loss of valuable topsoil. Additionally, the leaves and branches of trees slow down the force of wind, reducing the likelihood of soil erosion caused by wind. Therefore, trees are crucial in reducing erosion and preserving the stability of the land.Rate this question:

The ________________ of a tree serve to anchor it to the ground and gather water and nutrients to transfer to all parts of the tree.
-
Stem
-
Roots
-
Shoot
-
Leaves
Correct Answer
A. RootsExplanation
Roots serve to anchor a tree to the ground and gather water and nutrients to transfer to all parts of the tree. They play a vital role in providing stability and support to the tree, as well as absorbing water and minerals from the soil. The roots also help in storing nutrients and carbohydrates for the tree's growth and survival. Without roots, a tree would not be able to obtain the necessary resources for its survival and would be unable to grow and thrive.Rate this question:

The _____________ is also known as embryonic root
-
Plumule
-
Radicle
-
Stem
-
All of the above
Correct Answer
A. RadicleExplanation
The radicle is also known as the embryonic root. During germination, the radicle is the first part of the plant embryo to emerge from the seed. It grows downwards into the soil, anchoring the plant and absorbing water and nutrients. The radicle eventually develops into the primary root of the plant. Therefore, the correct answer is Radicle.Rate this question:

The radicle or embryonic root is the first part of a seedling to emerge from the seed during the process of _________________.
-
Germination
-
Fertilisation
-
Ovulation
-
Placentation
Correct Answer
A. GerminationExplanation
The radicle or embryonic root is the first part of a seedling to emerge from the seed during the process of germination. Germination is the process by which a seed begins to grow and develop into a new plant. It involves the absorption of water, activation of enzymes, and the emergence of the radicle, which anchors the seedling into the soil and allows it to absorb nutrients for further growth.Rate this question:

The tip of the finer roots are single cell ___________.
-
Phloem
-
Xylem
-
Root hairs
-
Scelerenchyma
Correct Answer
A. Root hairsExplanation
Root hairs are single-cell extensions that are found on the tip of finer roots. They play a crucial role in the absorption of water and nutrients from the soil. These thin, hair-like structures increase the surface area of the root, allowing for more efficient absorption. Root hairs are responsible for the majority of water and nutrient uptake in plants, making them essential for plant growth and survival.Rate this question:

________________ are referred to as breathing pores
-
Lenticel
-
Xylem
-
Phloem
-
Sieve tubes
Correct Answer
A. LenticelExplanation
Lenticels are referred to as breathing pores. Lenticels are small, raised structures found on the surface of stems, roots, and fruits of plants. They allow for gas exchange between the internal tissues of the plant and the external environment. This exchange is important for respiration in plants, as it allows oxygen to enter and carbon dioxide to exit. Lenticels are especially important in woody plants, where the outer layer of bark can be impermeable to gases. Therefore, lenticels play a crucial role in facilitating the breathing process in plants.Rate this question:

___________________ are structures specialised for photosynthesis
-
Stem
-
Trunk
-
Root
-
Leaves
Correct Answer
A. LeavesExplanation
Leaves are structures specialized for photosynthesis. They contain chlorophyll, which is responsible for capturing sunlight and converting it into energy through the process of photosynthesis. The flat and broad shape of leaves provides a large surface area for maximum absorption of sunlight. Additionally, leaves have tiny openings called stomata that allow for the exchange of gases, such as carbon dioxide and oxygen, which are essential for photosynthesis. Due to these adaptations, leaves are the primary organs in plants that carry out photosynthesis and produce food for the plant.Rate this question:

______________ is the tissue in most plants containing undifferentiated cells, found in zones of the plant where growth can take place.
-
Phloem
-
Xylem
-
Meristem
-
Collenchyma
Correct Answer
A. MeristemExplanation
Meristem is the tissue in most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Meristematic cells have the ability to divide and differentiate into various specialized cells, allowing for the growth and development of the plant. This tissue is responsible for the production of new cells, which then contribute to the growth of roots, stems, and leaves. Meristem plays a crucial role in plant growth and development.Rate this question:

A _____________ is an embryonic plant enclosed in a protective outer covering.
-
Flower
-
Seed
-
Stem
-
Root
Correct Answer
A. SeedExplanation
A seed is an embryonic plant enclosed in a protective outer covering. Seeds are formed from the fertilized ovule of a flowering plant and contain all the necessary genetic material and nutrients for the development of a new plant. The protective outer covering of a seed helps to safeguard the plant embryo from external factors such as desiccation, physical damage, and pathogens. Seeds are essential for the reproduction and dispersal of plants, as they can be dispersed by wind, water, animals, or other means, allowing the plant to colonize new areas and ensure its survival.Rate this question:
