6.
What do you count on a tree to tell its age?
Correct Answer
B. Rings
Explanation
Rings are counted on a tree to determine its age. Each year, a tree adds a new ring of growth around its trunk, which can be seen when the tree is cut or a core sample is taken. By counting these rings, it is possible to estimate the age of the tree. This method is commonly used in dendrochronology, the scientific study of tree rings, to determine the age of trees and analyze past environmental conditions.
7.
What tree grows from an acorn?
Correct Answer
C. Oak
Explanation
An oak tree grows from an acorn. Acorns are the seeds of oak trees, and when they are planted in the ground, they germinate and grow into oak trees.

8.
What orange pigment is found in fruits and vegetables?
Correct Answer
D. Carotene
Explanation

9.
What tissue is found on the surface of a plant?
Correct Answer
A. Epidermis
Explanation
The correct answer is Epidermis. The epidermis is a tissue found on the surface of a plant. It is the outermost layer of cells that covers the leaves, stems, and roots of a plant. The epidermis provides protection against water loss, pathogens, and physical damage. It also helps in the regulation of gas exchange and the absorption of nutrients.
10.
When a plant doesn't grow for some time, what is it called?
Correct Answer
B. Dormancy
Explanation
Dormancy is the correct answer because it refers to a period of inactivity or slowed growth in plants. During dormancy, a plant may temporarily stop growing due to unfavorable environmental conditions such as low temperature or lack of water. This period allows the plant to conserve energy and survive until conditions become more favorable for growth. Extinction refers to the complete disappearance of a species, gestation is the period of development in animals before birth, and germination is the process by which a plant begins to grow from a seed.
11.
What is it called when a plant sprouts?
Correct Answer
A. Germination
Explanation
Germination is the correct answer because it refers to the process by which a plant grows from a seed or a spore. During germination, the seed or spore absorbs water and begins to develop roots, stems, and leaves. This is the initial stage of a plant's growth and is essential for its survival and reproduction. Pollination, hybridization, and refrigeration do not accurately describe the process of a plant sprouting.
12.
What do ferns have instead of seeds?
Correct Answer
B. Spores
Explanation
Ferns reproduce through spores instead of seeds. Spores are tiny single-celled structures that are produced by ferns and released into the environment. These spores can germinate and develop into new fern plants under suitable conditions. Unlike seeds, spores do not contain an embryo and do not have a protective seed coat. Instead, they rely on external factors such as moisture and temperature to successfully grow into new fern plants. This method of reproduction is unique to ferns and some other primitive plant groups.
13.
Which structure is used to grow plants in climates too cold for them?
Correct Answer
C. Greenhouse
Explanation
A greenhouse is a structure that is specifically designed to create a controlled environment for plants to grow. It provides protection from cold temperatures, allowing plants to thrive in climates that would otherwise be too cold for them. The greenhouse traps heat from the sun, creating a warmer atmosphere inside, and also prevents heat from escaping. This enables plants to grow and flourish, even in colder climates. Therefore, a greenhouse is the ideal structure to use for growing plants in cold climates.
14.
What word means something to do with flowers?
