The organelle you're looking for should be cholorplasts.

Chloroplasts are double membrane bound organelles, which is important for the process so photosynthesis. The outer membrane is smooth and gives the shape of the chloroplast, while the inner membrane forms sac that contains chlorophyll inside.

Chloroplasts exists in green plants that photosynthesize for energy, and they appear the most in mesohpyll cells, a type of cells in leaf.

Defined as variation of life on Earth, biodiversity is the number and relative abundance of different species

Biodiversity is determined as the number of different species and the variation of their genetic material. If the number of species is high, then the biodiversity is also high. Area with high/rich biodiversity should be protected since it was home to many species. Using it for economical reason could lead to extinction of many creature.

Complete question:

Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited.

A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time.

Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child will also have the disease? Express your answer as a fraction using the slash symbol and no spaces (for example, 1/2).

Answer:

The probability that the second child will also have the disease is 1/16.

Explanation:

Available data:

Two genes independently inherited: one for blood type, the other for disease
Man with type A blood x Woman with type B blood
Both parents are heterozygous for the gene that causes the disease; Dd

If the man has A blood, and the woman has B blood, and they already have an affected child, this means that they must be heterozygous for blood type too.
