Chapter 3: The Structure of Living Things
1. Read the packet, pgs. 1-18. This is an excellent overview of all the topics on this
section of the NJASK.

7. This organism (flies) starts out as an egg, and it starts to grow and becomes maggots
(aka larvae). When the organism is an egg, it’s like when humans are babies. When they
become maggots, we are children. The flies then mature into pupae. That is around the
same stage in humans when we are adolescents. We mature into adults, and the flies
then grow into adult flies. We then reproduce, and so do the flies. The cycle starts all
over again, with babies or eggs. This pattern doesn’t take the same amount of time to
occur, but the same stages happen. The organisms go through metamorphosis.
8. The way to tell a difference of a plants’ cell or an animals’ cell is whether or not the
cells produce chloroplasts and chlorophyll. The plants use chloroplasts to produce sugar
to use as energy when the plant makes chlorophyll. Both of cytoplasm and chlorophyll
are used in plants to get energy and covert glucose into energy. We don’t have to use
either of them to get energy from the food we eat.
9. The diagram of cells on the left is probably the human or animal cell, (A). The cells on
the right are cells of a plant. The cells on the right have chloroplast and chlorophyll and
have a cell wall. The plant cells use chloroplast to make chlorophyll to use as energy. So
we don’t have to make our own food, we take the nutrients out of the food we eat, unlike
plants. The food we eat, we break down to use now and stored later. Vacuole larger in
plant cell, have chlorophyll, chloroplast, plant cells look like a brick wall, have a cell
wall and more organized. The plant cell doesn’t have the bone tissue. We have that
structure to move and be supported. Unlike plats, they don't have them to keep upright.

10. Reproduction is the one thing an individual organism doesn’t have to do in order to
survive. If they whole species want to survive, it has to reproduce. If the species is going
to survive, the organisms has to continue the species of organisms, otherwise there
won’t be anymore of that type of organism on the planet. Once that organism dies off,
there are no more of that kind. One animal will survive if it doesn’t reproduce, but the
whole species wouldn’t

1. They are baby flies from adult flies. They come from eggs of flies and have a food
source (the meat) to survive. The can only come from living flies.
2. There is no such thing. If is reproduction, from adult flies, the babies are born, they
need food to survive and therefore die without it.

7. The skeletal system protects the body, supports it, gives it the shape it has and gives
it the structure. If the skeletal system weren’t there, no muscle would be in the body
because it had nothing to attach to. Without muscles, the body wouldn’t be to move or
have tendons to help it bend.
8. Being an oxygen molecule I was inhaled and I passed through the Respiratory system
(lungs) and I was then moved into the Circulatory system (red blood cells) and passed
through the Nervous system on my way to the brain. I was used and took out the oxygen
to be used to pump orders throughout the body. Then I went back through the
Circulatory system in the red blood cells yet again. I was brought back to the respiratory
system to wait to be exhaled and be gotten rid of.
9. The cells like the red blood cells in the heart help provide oxygen-enriched blood to
pump around the body. Many of those cells make up a tissue, which make up an organ

the jobs it has to.

5. Chimpanzee because we’re in the same Phylum, Class, possibly order, Family and
Species. WE are built the same way and have almost the same bone structure.
6. He made a pneumatic devise for all the classification of the different kingdoms. This
way he would remember Kingdoms, Phylum, Classes, Order, Family Genus, and Species
and how to classify an organism. King Philip Came Over From Germany to Spain
