Plant Systems Notes
Questions:
Root and Shoot Systems
Plants have two separate systems:
1.
Shoot System:
_____________________________________________________
2.
Root System:
______________________________________________________
Plant Tissue Types
Summary:
 _________________Tissue: “Plant skin,” the outermost layer, protects the
plant
 _________________Tissue:
“Plant veins,” made up of
xylem (carries water/minerals)
and phloem (carries food)
 ______________________:
everything else, all cells
between dermal and vascular
layers
 ________________________:
found in tips of roots and
shoots, is where growth occurs
Questions:
Root
Works to anchor the plant and allows the
plant to absorb food, water, and minerals
(micronutrients)
There are ______________ types of roots:
1. ________________________ – absorb
deep water and store nutrients
2. ________________________– absorb
water and support soil (more efficient
than taproots)
Stem
___________________________ water, minerals and food throughout the plant.
Also helps support leaves.
Xylem and Phloem make up the ___________________________________
(nutrient transport system) of the plant
______________________________________ transports water and minerals UP
the plant.
______________________________________ transports food up AND down the
plant.
Summary:
Movement of Water in Stem
Questions:
Xylem are able to transport ____________________ from the roots _______ due
to 2 actions:
1.
_________________ and _____________________ which create
_________________________________________________.
2.
_____________________________________ which occurs when water
evaporates from the underside of leaves and creates a
________________________________ similar to a straw.
Leaves
Leaves are __________________________________________ for plants – they
absorb sunlight to make food using chlorophyll (green pigments in chloroplast
that absorb sunlight)
Summary:
Questions:
The ___________________ is the top waxy layer of the leaf, it helps prevent the
loss of water.
The _____________________________________ are the cells that do most of
photosynthesis.
The ________________________ are openings that allow gases to pass through,
they are surrounded by ______________________________________________.
Photosynthesis and Cellular Respiration
Notice the ______________________ of photosynthesis are the
______________________ of respiration AND the _______________________
of respiration are the _______________________ of photosynthesis
Flower
Flowers are the _____________________________________________ organs for
plants. The petals are designed to
_______________________________________________ like bees and
hummingbirds.
Summary:
Questions:
Male Organs of a Flower
The _________________________ is the male component of a flower, it is made
of:
 ______________________________- creates pollen (sperm cells = Male
GAMETE)
 ______________________________- supports anther
Female Organs of a Flower
The ___________________________ is the female component of a flower, it is
made of:
 __________________________- sticky surface for pollen
 __________________________- contains ovules/eggs (Female GAMETE).
Becomes a fruit to help spread seeds
 __________________________- links the stigma to the ovary
Summary:
Questions:
Pollination
Pollination is when the male _______________ (sperm) transfers to the female
____________ (ovules/eggs).
This can happen in 2 ways:
__________________________carries pollen to its destination. This is a
__________________ ____________________________________ and requires a
lot of pollen production.
An _______________________carries the pollen to its destination. This is
________________ ___________________________________and does NOT
require a lot of pollen production.
Fertilization
Just like in humans, fertilization occurs when a sperm cell and egg cell come
together. Sperm and egg are sex cells which are called
_____________________________________________.
It takes 1 sperm and 1 egg to form a ___________________________, which is a
fertilized egg.
This egg contains a full set of __________________________________________
which is called being ____________________________.
We refer to diploid cells as having __________ chromosomes.
This means that the sperm and egg
each only have a
____________________ of
chromosomes which is called being
_______________________________.
We refer to haploid cells as having
_____________ chromosomes.
