Cell Parts
What part of the cell contains the genetic material?
Nucleus
What is the main pigment used in photosynthesis?
chlorophyll
What process do cells use to break down glucose for energy?
Cellular Respiration
What is the smallest unit of life?
a cell
What type of reproduction results in genetically identical offspring?
asexual reproduction
Which organelle is known as the powerhouse of the cell?
mitochondria
What gas do plants take in for photosynthesis?
carbon dioxide
What is one way cells can release energy without oxygen
Fermentation
Name the system in the body responsible for transporting blood.
the circulatory system
How does sexual reproduction lead to genetic variation?
it combines genes from two parents
What structure provides support and protection to plant cells
cell wall
What are the products of photosynthesis?
glucose and oxygen
What are the main products of cellular respiration?
carbon dioxide, water, and energy (ATP)
How do the nervous and endocrine systems work together?
they both regulate body functions and responses
Describe one reproductive cycle in plants.
the flowering and seed production cycle
Which organelle is responsible for photosynthesis in plant cells?
chloroplasts
Explain how light energy is converted during photosynthesis.
light energy is converted into chemical energy in glucose
Describe how energy is conserved during cellular respiration.
energy from glucose is converted into ATP, which cells use
List the levels of organization in the body from smallest to largest.
cells, tissue, organs, organ systems, and organism
What is the role of seeds in plant reproduction?
they help in dispersal and the continuation of species
How do the cell membrane and cell wall differ in function?
the cell membrane controls what enters/exits, while the cell wall provides structure
Why is photosynthesis important for ecosystems?
it produces oxygen and is the basis of the food chain
How does cellular respiration relate to photosynthesis?
they are opposite processes; photosynthesis stores energy, respiration releases it
What might happen if one body system fails to work properly?
it can disrupt the function of other systems and harm overall health
Explain the significance of genetic variation in a population.
it increases adaptability and survival chances
