1) State whether plants perform cellular respiration and explain why or why not. 2)Explain which cell would likely contain more mitochondria, a muscle cell or a skin cell. Use your knowledge of energy; mitochondria and their function to support your answer.

1) plants use photosynthesis to produce glucose, but the use cellular respiration to release energy from glucose so yes they do perform cellular respiration

2) a muscle cell because mitochondria is the site of cellular respiration (releasing energy from glucose) and they need more energy for muscle contraction

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

tissue

explanation:

it is actually formed by geoup of cells which is tissue
