Plants Review - #1
When a plant begins the process of germination, describe what it is doing.
The germinating plant is starting to sprout and grow. In both monocots and dicots, this process starts with the root extending from the seed. Slide3
Plants Review - #2
You notice that the large leafed plant in your house needs to be watered much more often than the small leafed plant. Both plants are the same height and width. Explain why this is the case and be sure to name the process involved!
Transpiration is the process
of plants releasing
excess water through the stomata in their leaves.
The plant with more leaf surface area has more stomata and will release more water, so it needs to be watered more often.
Stomata
also let in the carbon dioxide needed for photosynthesis and let out the oxygen
.Slide4

All species of organisms that reproduce sexually, undergo a process called fertilization. What is it and how does it work in plants?
Fertilization occurs with the nucleus of a sperm cell (male) joins with the nucleus of an egg cell (female).
In plants this happens when pollen (sperm) enters the stigma and joins with one of the many ovules (eggs) inside of
the ovary. Slide5
Plants Review - #4
Humans consume and digest food to gain the energy needed to perform life processes. Name and explain the process that plants use to gain energy.
Photosynthesis is the process that plants use to transform light energy from the sun into chemical energy they can use.
This is done by combining carbon dioxide, water and sunlight.
The products of photosynthesis are
oxygen and glucose (sugar).
Chloroplasts are the organelles
that perform this process. Slide6
Plants Review - #5
Define pollination and explain the different types in detail.
Pollination is the process of pollen being transferred from the male part of a plant (stamen) to the female part (pistil).
There are two types.
Cross-pollination happens when the
pollen
from one plant is transferred to the
pistil
of another, usually by
an
animal or wind.
Self-pollination happens
when
pollen from a flower
enters
its own pistil. Slide7

In a plant’s life cycle it will undergo 5 major processes. Imagine that it is starting as a dormant seed.
P
ut these processes in order of occurrence and be ready to defend/explain your decisions. Fertilization, Photosynthesis, Germination, Pollination, Transpiration
Germination
Photosynthesis/Transpiration Pollination Fertilization
Germination comes first because the plant must grow before it can perform any of the other processes.
Photosynthesis and Transpiration begin as soon as the plant has leaves and continue throughout the plant’s life cycle.
Pollination happens when the plant has matured enough to reproduce.
The process of transferring pollen leads to fertilization. Slide8

Describe some differences between vascular and non-vascular plants.
Non-vascular plants
hug the ground or live in VERY wet climates
no roots or stems with xylem & phloem to pull water
algae (live in water) and mosses/ liverwort plants (live nearby water)

Describe some differences between vascular and non-vascular plants.
Vascular plants
usually tall
have roots and stems that pull water up into the plant
Examples are
ferns/ horsetails/ gymnosperm & angiosperm plants

Plants Review - #8
Describe some differences between gymnosperm and angiosperm plants.
Gymnosperm plants
Typically have cones which hold the seeds (naked seeds)
Can grow tall
Typically have leaves in a needle shape
Examples are
pine/ Western Red Cedar/ Douglas Fir/ Hemlock

Describe some differences between gymnosperm and angiosperm plants.
Angiosperm plants
Typically have flowers and/ or fruit (of some kind) which protect the seeds
Can grow tall
Typically have leaves in a broadleaf shape
Examples are
bean/ corn/ rose/ cherry/ sunflower

Describe some parts of a flowering plant.
Pistil & Stamen
Pistil holds the female portion of flower – style, stigma, ovary, ovule
Stamen holds the male portion of flower – filament, anther (pollen)
Examples are
Wisconsin Fast Plant/ corn/ bean

Describe some differences between monocot and
dicot
plants.Monocot
Seed stays underground after germination
Roots grow randomly out from base of stem
Xylem/ phloem spaced randomly
Leaf veins are parallel
urbanext.illinois.edu
fineartamerica.com
Flower groupings are typically in threesSlide14
Plants Review - #10
Describe some differences between monocot and
dicot
plants.Dicot
Seed grows up out of ground after germination
Tap root grows down deep – roots branch out
Xylem/ phloem arranged in a ring
Leaf veins are branching

Flower groupings are typically in fours or fives
