Answer: Diploblastic animals have radial symmetry.

Phylum porifera lack body symmetry and are therefore call asymmetrical this is because their bodies lack true tissues, true organs and there body is well adapted for water and water flows through their body and deposit nutrients needed for growth and development.

Explanation:

Diploblastic organisms meaning organisms that have two germ layers(ectoderm and endoderm) have radial symmetry because their symmetry is located along a central axis examples are the sea anemone and jelly fishes belonging to phylum cnidarians.

Phylum porifera e.g sponges are assymetrical that is they have no body plans and this is because the shapes of their bodies is adapted to water and water flow allow nutrients to enter their body for growth.

Explanation:

The arrangement of leaves that provide maximum exposure to sunlight is referred to as leaf phyllotaxy that reduces overlapping and overshadowing of leaves and supports maximum photosynsthesis.

The contains numerous chlorophyll molecules that trap the light energy for the oxidation of water and producing oxygen (O2) atoms required for carbon (IV) oxide reduction in light-independent, which takes place in the stroma of the chloroplast.

Hence, the correct answer in a sequential manner is as follows:

phyllotaxy

photosynthesis

chloroplasts

chlorophyll

energy

oxidation

oxygen

reduction

independent

The constancy of the chromosome number from one cell generation to the next is maintained through.

vesna_86 [32]

Through mitosis, the number of chromosomes is kept constant from one cell generation to the next.

<h3>What occurs during mitosis?</h3>

A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.

<h3>How many phases of mitosis are there?</h3>

Prophase, pro metaphase, metaphase, anaphase, and telophase are these stages.

<h3>What function does mitosis serve?</h3>

Mitosis' purpose is to divide the genome so that the two daughter cells inherit an identical and equal number of chromosomes.

<h3>Where in the cell cycle does mitosis occur?</h3>

The mitotic phase, which consists of mitosis and cytokinesis and produces two daughter cells, begins after interphase. Despite the fact that the two processes frequently overlap, mitosis occurs before cytokinesis.
