Grade 11 Term 2 Life Sciences Revision

These flashcards cover critical concepts in Life Sciences related to photosynthesis, respiration, and human nutrition.

Photosynthesis

The process by which chlorophyll in the chloroplasts absorbs sunlight to convert carbon dioxide and water into glucose and oxygen.

ATP

Adenosine triphosphate, which serves as an energy carrier in cells.

Aerobic respiration

A process of cellular respiration that occurs in the presence of oxygen, yielding carbon dioxide, water, and ATP.

Anaerobic respiration

A process of cellular respiration that occurs without oxygen, producing lactic acid in animals or alcohol and carbon dioxide in yeast.

Light phase

The part of photosynthesis occurring in the grana of chloroplasts, where light energy is used to split water molecules.

Dark phase

The part of photosynthesis that occurs in the stroma of chloroplasts, where carbon dioxide is converted into glucose.

Homeostasis

The regulation of internal conditions, such as blood sugar levels, in a stable state.

Dentition

The arrangement and condition of teeth, which varies between herbivores, carnivores, and omnivores.

Mechanical digestion

The physical process of breaking down food into smaller particles, which includes chewing and churning.

Chemical digestion

The process of breaking down large food molecules into smaller, soluble molecules with the help of enzymes.
