Llana [10]

Answer:

The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.

Explanation:

As you can see in the attached table

1. For the size of the flagella we gave that:

- 241 organisms have long flagella

- 79 organisms have short flagella,

As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.

2. For the number of vacuole we have:

- 247 organisms have one vacuole

- 73 organisms have two vacuole

As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.

Then

Dominant phenotypes = Long flagella and one vacuole

Recessive phenotypes = Short flagella and two vacuoles

(i) Label port A
just olya [345]

Answer:

1) pollen grain (A), stigma (B), pollen tube (C), Ovary (D)

The pollen grain is a male reproductive part while ovary is the female reproductive part.

2) When a pollen grain lands on the stigma of a flower, a pollen tube begins to grow. It grows through the style until it reaches an ovule inside the ovary.

3) The pollen tube is a tube that transports the male gamete cells from the pollen grains to the ovule (female gamete) inside the ovary.

The nucleus of the pollen passes along the pollen tube and fuses with the nucleus of the ovule. This process is called fertilisation.

4) After the fertilisation, female parts of the flower develop into fruit and ovules become seeds.
