Biology - First Semester - Freshman Year

What are the characteristics of life that organisms must meet to be considered living?

Organisms must be made up of cells, reproduce, based on genetic code, grow and develop, obtain and use materials and energy, respond to the environment, maintain a stable internal environment, and evolve.

What is the smallest unit that can be considered alive?

Cells are the smallest unit that can be considered alive.

What is the difference between sexual and asexual reproduction?

Sexual reproduction requires two cells from different parents, while asexual reproduction involves one parent splitting off a portion of itself.

What is homeostasis?

Homeostasis is how organisms maintain stable internal conditions despite external changes.

What is the role of chlorophyll in photosynthesis?

Chlorophyll captures sunlight for photosynthesis.

What is the primary purpose of photosynthesis?

Photosynthesis converts light energy into chemical energy, producing glucose and oxygen.

What are the four main types of macromolecules?

Carbohydrates, lipids, proteins, and nucleic acids.

What is the main function of enzymes?

Enzymes speed up chemical reactions in our bodies.

What type of organism is a detritivore?

Detritivores are organisms that eat dead and decaying organisms.

What is mutualism?

Mutualism is a symbiotic relationship where both organisms benefit.

What is the cell membrane's function?

The cell membrane regulates materials entering and leaving the cell.

What does the law of conservation of matter state?

Matter cannot be created nor destroyed; it can only change forms.

What is a trophic level?

A trophic level represents a step in the flow of energy and nutrients in an ecosystem.

How do plants primarily obtain water for photosynthesis?

Plants obtain water from the soil, absorbed by their roots.

What is the primary product of photosynthesis that provides energy to plants?

The primary product of photosynthesis is sugar (glucose).
