Biology

4. – A type of cell that contains a cell wall, chloroplasts, and a vacuole.
5. – Having two identical alleles for a trait (e.g., BB or bb).
6. – Found in plant cells, where photosynthesis takes place.
7. – A trait that is expressed if at least one dominant allele is present.
10. Wall – Found in plant cells, providing structure and support.
11. A type of cell that does not have a cell wall or chloroplasts.
14. – The control center of a cell that contains DNA.
15. – The basic unit of life in all living organisms.
16. – The physical characteristics of an organism (e.g., brown eyes, tall plant).

1. – Having two different alleles for a trait (e.g., Bb).
2. – The powerhouse of the cell where energy is produced through respiration.
3. Acid – The molecule that carries genetic instructions.
6. – The jelly-like substance where chemical reactions take place.
8. – A trait that is only expressed if two recessive alleles are present.
9. – Small structures that produce proteins.
12. Membrane – The thin layer that controls what enters and leaves the cell.
13. – The genetic makeup of an organism (e.g., Bb, TT).
