A punnet square is used to visually see the dominant and recessive traits. Mendel's law says that alleles pair independently during the formation of gametes (aka sex cells). This means that traits are transmitted to offspring independently of one another.
A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.
Answer:
1. Roots: anchor the plant in soil and absorb water and minerals
2: Stem: Holds the plant upright and bear leaves, branches and fruits.
3. Leaves: Carry out photosynthesis to make food for other plant parts.
4. Flower: serves as organ of reproduction to maintain the continuity of the species.
Explanation:
1. Roots: The cells of roots are specialized to penetrate the soil deep to anchor the plant and absorb water and minerals for nutrition of plants.
2: Stem: The cells of stem impart mechanical strength to keep the plant upright and bear leaves, branches and fruits.
3. Leaves: Cells of leaves have chlorophyll pigment to carry out photosynthesis to make food for other plant parts.
4. Flower: Some of the cells of flowers produce male and female gametes that fuse leading to seed formation. Seed germination maintains the continuity of the species.
