this PowerPoint presentation was all about the gas exchange in plants and animals. this topic was good for general biology one in senior high school especially in grade 11 but it is also good for hinger levels

1. in plants and
animals

2. • Plants exchange gases through tiny pores
called stomata, primarily located on the
underside of leaves. Each stoma is surrounded
by guard cells, which regulate its opening and
closing.
• In animals, they exchange gases through
specialized respiratory organs like lungs, gills,
or skin depending on the species.

3. During photosynthesis, plants absorb carbon dioxide from the
atmosphere through stomata, while oxygen is released as a
byproduct. During respiration oxygen is taken in, and carbon
dioxide is released through the same stomata.
In animals with lungs, oxygen is taken in through
inhalation, diffuses into the bloodstream through the alveoli,
and is transported to cells. Carbon dioxide is then released
from cells into the bloodstream, transported to the lungs,
and inhaled during exhalation.

4. • In animals, there is a respiratory organs (like
lungs, gills, etc.) present within the body,
where exchange of gases occurs. No such
respiratory organ is present in plants. The
tissues of a leaf are adapted for photosynthesis
and gas exchange.
• The carbon dioxide produced in animals during
respiration is released to the atmosphere,
whereas the carbon dioxide produced during
the plant respiration may be used by the plant
for carrying out photosynthesis.
