What are angiosperms? - ✔✔✔ Correct Answer > Flowering plants in
which the seed in enclosed within a fruit wall
Parts of the male reproductive system: - ✔✔✔ Correct Answer >
Testes: produce sperm and sex hormones that control both
reproduction functions and secondary sexual traits
- After sperm is produced, they travel from each testis through a duct
called the epdidymis where they completely mature
Vas deferens: transports mature sperm to the urethra
Urethra: tube that carries urine or sperm to the outside of the body
What are invertebrates? - ✔✔✔ Correct Answer > Lack an internal
skeleton
- evolved first and outnumber vertebrates
What is fungi? - ✔✔✔ Correct Answer > Non-green, heterotrophic
organisms that grow in dark, moist habitats
,- Do not have chloroplasts, can't photosynthesis, are multi cellular
eukaryotes and more closely related to animals rather than plants
Ex: Mushrooms, molds, yeast
Parts:
Mycelium: vegetable part that consists of a network of fine white
filaments (hyphae)
Hyphae: Create an expanded surface area, allowing them greater
efficient in extracting water and nutrients form soils
What are protostomes? - ✔✔✔ Correct Answer > Characterized by
spiral cell division when the embryo first forms and a Elastoplast
becomes the mouth
- Mouth is the first opening (proto, before)
- Ex: flatworms, roundworms, mollusks, arthropods
What are deuterostomes? - ✔✔✔ Correct Answer > Characterized by
radial cell division when he embryo first forms and a blastoplore
becomes the anus
- Second opening (deutero, second)
- Ex: echinoderms, chordates
Describe the evolution of chrodates: - ✔✔✔ Correct Answer > The
earliest chordates were all marine animals. As chordates continued to
evolve, they spread to freshwater habitats and to land. The amphibians
represent an intermediate phase in the water to the land transition of
,chordates. The evolution of birds further increases the disturbed of
chordates by expanding their populations into sky habitats.
Explain the imporatint classifications of primates: - ✔✔✔ Correct
Answer > Prosimians- lemurs and tarsiers
Anthropoids- monkeys, apes and humans
Hominids- apes, chimpanzees and humans
Hominins- humans
Explain the innovations that lead to the evolution of hominins - ✔✔✔
Correct Answer > Bipedal: had a small brain but walked upright on 2
legs
Tool Use Is certain to have made tools and may have been the first to
exhibit culture
Increased brain size: Double the brain size and may have been the first
to control fire and use more complex tools
What is the epidermis? - ✔✔✔ Correct Answer > Outside of a plant
that is made up of a single layer of cells
- Cells exposed to air are covered with a waxy cuticle which restricts
water loss
What is ground tissue? - ✔✔✔ Correct Answer > Make up the bulk of
the plant body- includes 3 types of simple tissue:
, Parenchyma cells: have thin walls and are active in photosynthesis and
storage
Collenchyma cells: provide support for primary tissues
Sclerenchyma cells: Fibrous cells that give stalks their gravity-resisting
strength
What is vascular tissue? - ✔✔✔ Correct Answer > Composed of 2
types of tissues
Xylem: conducts water and dissolved minerals through the plant body
Phloem: Conducts sugars and other solutes throughout the plant
Explain how water is transported through plants - ✔✔✔ Correct
Answer > Cohesion-tension model: Water and minerals in solute are
taken up in root hairs and then transported upward in xylem
Transpiration: as dry air crosses a lear surface when stomata are open,
water in the plant evaporates in the air
Explain the different plant responses - ✔✔✔ Correct Answer >
Phototropism: causes plants to turn toward light
Gravitropsim: causes plant stems to curve away from gravity
Explain the different plant hormones: - ✔✔✔ Correct Answer >
Chemical signals that cause responses within plant cells and tissues
Auxin's: soften cell walls to allow growth
