Topic 3 Random
Plants respond to _______ in order to grow
stimuli
What type of reproduction involves two parents and results in offspring not genetically identical to the parent.
What is sexual reproduction
Describe 3 ways flowering and nonflowering plants SEEDS can be dispersed.
What is wind, water and animals
What is the difference between learned vs instinctive behavior?
learned is taught within an animal's lifetime, and instinctive is innately known without being taught.
WHich way do the roots and shoots grow on a plant?
Roots = with gravity
shoots = against gravity
What are some advantages of asexual reproduction?
What is fast reproduction, and does not require a mate.
What is it called when pollen reaches the stigma of another plant?
What is pollination
Why might animals migrate?
moving to areas with more mates, better climate, more food opportunities
What are some factors that could affect an animal's growth, and provide an example? Explain if your factor is genetic or environmental
space, nutrients (food and water), genes, disease
What is a zygote?
What is it has received half of its chromosomes from one parent and half from the other parent.
What are two major groups of plants based on reproductive structures?
What are seed (angiosperms, gymnosperms) and seedless plants (vascular, nonvascular)
What is the difference of internal vs external fertilization and provide an example animal for each
1. internal: inside the parent's body - humans, elephants, gorillas
2. externa: outside the parent's body - most fish, some reptiles
Why might a tree go into dormancy and what happens while a tree is dormant
lack of liquid water or freezing temperature. The tree doesn't grow!
Many plants can reproduce both sexually and asexually. For example, rose bushes reproduce asexually when cuttings planted in the ground grow roots and become a new rose bush. They can also reproduce sexually when their flowers are pollinated. What is the primary advantage of sexual reproduction in roses?
What is genetic variation
Explain the differences between gymnosperm and angiosperm reproduction/fertlization process
1. Gymnosperms - exposed seeds on cones that can be fertilized by pollen through wind
2. angiosperms - protected seeds within a plant's ovary; these plants produce flowers that aid in attracting pollinators for fertilization
When animals perform behaviors like bird songs, warning calls, or body movements to send information to others, this is called ________ and why might some animals may need to do this?
communication - mating purposes, parenting purposes, communicating with others (territory, mates), or show dominace
Promiscuity - many males, and many females (corals, mice)
polygyny - one male with many females (lions)
monogamy - one male and one female (albatrosses, wolves)
Polyandry - one female and many males (honeybee queens, merkats)
3 differences between mitosis and meiosis.
1. Mitosis produces genetically identical daughter cells, vs mieosis produces genetically unique daughter cells
2. Mitosis makes cells have 46 chromosomes vs. meiosis males cells with half the needed chromosomes
3. Mitosis goes through PMAT once, Meiosis goes trhough PMAT twice
Modern grocery store strawberries have been selectively bred to produce large, brightly colored fruit. When varieties with desired traits are developed, plants are propagated by asexual reproduction. Write your answer on the lines. What is one advantage to farmers of producing fruit for grocery stores using this method?
What is producing a large amount of strawberries with a desirable trait.
Can ensure the offspring would also be large and brightly colored.
Pros and Cons of cooperative behavior
1. pro: more adults protecting the young, shared responsibilities
2. cons: only as strong as your weakest link, may bring more attention towards self
