Plant Life Cycle Quiz Questions

Explanation
An organism is a living entity that exhibits the six features of life, which include being composed of cells, having the ability to grow and develop, maintaining homeostasis, responding to stimuli, reproducing, and obtaining and using energy. The options "cotyledon," "animal," and "antibody" do not encompass all these features and therefore cannot be considered organisms.

Explanation
Water is the only thing necessary for germination because it activates enzymes that break down stored food in the seed, allowing it to grow. Without water, the seed remains dormant and cannot begin the process of sprouting. Soil provides nutrients and support, air supplies oxygen, and sunlight is essential for photosynthesis, but water is the key factor that triggers germination.

Explanation
The root of a plant grows first because it is responsible for anchoring the plant in the soil and absorbing water and nutrients. The root system also provides stability and support for the plant as it grows. Without a well-developed root system, the plant would not be able to survive and grow properly.

Explanation
Plants need sunlight for photosynthesis, water for hydration and nutrient absorption, air for respiration, and nutrients for growth and development. Therefore, all of the above options are correct as they are essential requirements for plant growth.

Explanation
Germination is the process by which a seed begins to grow into a new plant. It involves the sprouting of the seed and the development of a root, stem, and leaves. Therefore, germination is another name for sprouting. Pollenation refers to the transfer of pollen from the male to the female reproductive organs of a plant. Rooting refers to the development of roots, while stemming refers to the growth of stems.

Explanation
The fruit protects the seed. When a flower is fertilized, the ovary of the flower develops into a fruit, which surrounds and protects the seeds. The fruit provides a protective covering that helps to prevent damage from physical factors such as wind, rain, and animals. It also plays a role in seed dispersal, as animals may eat the fruit and spread the seeds to new locations.

Explanation
Carrots are classified as vegetables because they do not have seeds. Fruits are typically defined as the mature ovaries of flowering plants that contain seeds. Carrots, on the other hand, are root vegetables that grow underground and do not produce seeds. Although carrots are orange and not juicy, these characteristics are not the defining factors for classifying them as fruits.

Explanation
The correct answer is embryo. The embryo refers to the baby plant inside the seed. It is the early stage of development for the plant, containing the essential structures and tissues that will eventually grow into the mature plant. The embryo is protected by the seed coat and contains the cotyledons, which are the first leaves of the plant.
