As the pollen tube penetrates the ovule, it releases two sperm cells. ... As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization

A group of fibers inside the cell that helps support the cell is the _____. microtubule flagella cytoskeleton filament
Ber [7]

Answer:

Microtubule fiber

Explanation:

Microtubules play a huge role in movement within a cell. They form the spindle fibers that manipulate and separate chromosomes during the mitosis phase of the cell cycle. Examples of microtubule fibers that assist in cell division include polar fibers and kinetochore fibers.

The primary function of a flagellum is that of locomotion, but it also often functions as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. The similar structure in the archaea functions in the same way but is structurally different and has been termed the archaellum.

The Cytoskeleton  is a dynamic three-dimensional structure that fills the cytoplasm. This structure acts as both muscle and skeleton, for movement and stability. The long fibers of the cytoskeleton are polymers of subunits.

The opposite term is filament fibre, which is fibre that comes in continuous to near continuous lengths for use. Silk, taken from the cocoon of a silkworm, is a filament. Synthetic fibres can also be manufactured as filament. If the filament is then cut into discrete lengths, it becomes staple fibre.

Hope this helps : D
