Quiz: Life Cycles Of Plants And Animals

Explanation
The first stage in the life cycle of most animals is an egg. This is where the animal begins its development and grows inside the protective shell. The egg provides the necessary nutrients and protection for the growing embryo until it is ready to hatch. It is the starting point of the life cycle and the beginning of the animal's journey towards adulthood.

Explanation
The correct answer is "wings" because the statement mentions that the nymph looks like the adult, which implies that they have similar physical characteristics. However, it also states that the nymph usually has no offspring, which suggests that it is not fully developed or mature. Since wings are typically a feature of adult insects, it can be inferred that the nymph does not have wings.

Explanation
The second stage of incomplete metamorphosis is the nymph stage. In incomplete metamorphosis, the insect does not go through a complete transformation from larva to adult. Instead, it hatches from an egg into a nymph, which resembles a miniature version of the adult. The nymph gradually grows and undergoes a series of molts until it reaches its final adult form. Therefore, the correct answer is nymph.

Explanation
Metamorphosis refers to the process in which certain organisms undergo a distinct change in form during different stages of their life cycle. This change can involve various physical and structural transformations, such as the transformation of a caterpillar into a butterfly or a tadpole into a frog. It is a crucial process for many species as it enables them to adapt and survive in different environments and fulfill their specific ecological roles.

Explanation
The correct answer is larva because it is the stage that comes after the egg in metamorphosis. Larvae are wormlike forms that undergo further development before transforming into adults.

Explanation
Birds and turtles both undergo a similar life cycle that involves laying eggs. Both birds and turtles lay eggs, which then hatch into young offspring. These offspring grow and develop over time, eventually reaching adulthood. This is similar to the life cycle of birds, where they lay eggs, and the eggs hatch into chicks that grow and mature into adult birds. Therefore, the life cycle of a bird is most similar to that of turtles.

Explanation
An organism that is fully grown is called an adult. This term is used to describe an organism that has reached its full size and development, and is capable of reproducing. In the life cycle of many organisms, such as insects, there are different stages of growth and development. The larva and nymph stages come before the adult stage, during which the organism undergoes metamorphosis and matures into its final form. Therefore, an adult is the correct term to describe a fully grown organism.

Explanation
Germination is the correct answer because it refers to the stage when a plant begins to grow from a seed. During germination, the seed absorbs water and swells, causing the outer covering to break open. This allows the root to emerge and anchor the plant into the soil, while the shoot grows upward towards the light. At this stage, the plant is not yet a seedling or a young plant, and it is far from being a mature plant.

Explanation
The job of the pupa is to undergo metamorphosis and transform into an adult. During this stage, the pupa undergoes significant physiological changes and development, including the formation of wings, reproductive organs, and other adult characteristics. It does not eat or reproduce during this stage. Therefore, the correct answer is "to change into an adult."

Explanation
The correct answer is "life span" because the question states that an elephant lives longer than a mouse. The term "life span" refers to the length of time an organism is expected to live. In this context, it makes sense to use "life span" to describe the difference in longevity between an elephant and a mouse.

Explanation
The job of an adult is to reproduce. This means that their main purpose is to create offspring and continue the cycle of life. While eating and growing are important for survival, the ultimate goal for adults is to ensure the survival of their species by reproducing. Therefore, the correct answer is "to reproduce."

Explanation
The word organism refers to a living thing. It encompasses all forms of life, including plants, animals, and microorganisms. Organisms are characterized by their ability to grow, reproduce, and respond to stimuli from their environment. This term is used to describe any individual entity that exhibits the fundamental characteristics of life.

Explanation
The statement "People go through metamorphosis" is false. Metamorphosis refers to a biological process where an organism undergoes a complete change in form and structure. While some animals, such as butterflies and frogs, go through metamorphosis, humans do not. Humans go through stages of growth and development, but they do not experience a complete transformation like metamorphosis. Therefore, the correct answer is false.

Explanation
In a life cycle, organisms go through different stages of growth and development. To grow or reach the next stage in this cycle is to develop. This implies that the statement "To grow or reach the next stage in a life cycle is to develop" is true.

Explanation
Seeds need several factors to grow, including oxygen, moisture, sunlight, and the right temperature. Oxygen is necessary for the process of respiration, which provides energy for growth. Moisture is essential for seed germination and helps in the absorption of nutrients. Sunlight is required for photosynthesis, the process by which plants convert light energy into chemical energy. The right temperature is crucial for the enzymes and metabolic processes involved in seed growth. Therefore, all of the above factors are necessary for seeds to grow.
