Zanzabum

Answer:

Different genes are expressed in different cells

Explanation:

The instruction is provided to the cell by the genetic material in the form of genes. Genes are the physical segment present on the DNA which can code for a specific protein.

The genes are present in the cells in the condensed form called chromosome which is present in all the cells of the body.

Although all the cells contain the same type of chromosomes or genes but they differentiate to perform different functions.

The differentiation process involves the expression of different genes in different cells as a result of which different proteins are formed in different cells and they perform different functions.

How many and what are the processes that seed plants use to reproduce.
Luba_88 [7]
Plants reproduce through the process of fertilisation. Fertilisation is the process where female and male cells join together to form an embryo inside the seed. The seed protects the embryo in preparation for germination when conditions permit the plant to produce new plants.

Seed plants are classified into two types to determine reproduction. First are the Angiosperms, this type of seed plant has flowers that have special structures for reproduction. Pollens are made by male cells, while ovules are made by female cells. Pollens are carried out through the process of pollination (e.g. wind blows, insects carrying pollen). Most angiosperms that don’t undergo pollination develop intro fruits. If it goes into pollination they become new flowering plants.
<span>
Second classification is the Gymnosperms, which are seed plants that are held in cones. Gymnosperms like Angiosperms also have male and female reproductive cells. Reproduction also occurs through pollination but most gymnosperms are trees. The best example of a gymnosperm are pine cones.  </span>
