What Plants to Grow
Starting a garden can be tough and it takes
up a lot of your time. When saving your planet you
will need to replenish the oxygen. The best way to
accomplish this is to plant trees because they
produce more oxygen than your average bush. The
trees you should plant are apple, orange, avocado,
and pear. These trees not only produce oxygen but
they also produce fruit that have many purposes.
Also you should plant tomatoes, aloe vera (for
healing and moisturizing), rosemary bush (for
cooking), grapes, blackberry bushes, and cabbage.
These plants will get your planet back on track.
The Pollination Process
Plants reproduce through a process
called pollination. First, pollen falls onto the
stigma and over time the sperm cell and the
egg cell unite inside the plants ovule. Once
the plant is fertilized the ovary begins to
swell and eventually turns into a fruit.
There is one type of pollination called hybrid
pollination in which the pollen comes from a
different species. There is also Crosspollination which is the process of when the
pollen from one plant lands on another
plants stigma.
Plant Classification
Plant Uses
Plants have many uses. They produce
oxygen. Some produce fruits and vegetables.
They are great for cooking or just eating
straight from the plant. Some plants are good
for your skin and others are good for healing.
These plants also help to hold on to the soil to
prevent landslides, and animals make their
homes in them or around them. They provide
shade for people on hot day, and some can be
used to make paper or plastic. Most
importantly they can be used to make houses.
Plants are classified by a system
called binomial nomenclature. This system
consists of giving plants and living things
two names, a genus and species. Both of
the names are expressed in Latin. The
genus is the family name and the species is
the specific name that describes the genus.
Plants are also given a common name that
is not in Latin which we know them by.
Plants are given these names according to
their similarities and differences. When
classifying these plants into their genus
and species scientists often use branches.
Some branches botanists might use to
classify plants are whether they flower or
don’t, and whether they produce seeds or
not. They also distinguish plants by weather
they have parallel veins or net veins. These
are just a few branches the scientists might
use.

Hydroponics
Hydroponics is a method of growing plants in a
nutrient solution not soil. Hydroponics is useful
because the solution has essential mineral
nutrients. Also hydroponics is used in biology
research and teaching. Another thing
hydroponics is useful for is that it helps grow lots
of plants in a minimal amount of space and it’s
great for water conservation because you can
reuse the water.
The Parts of a Plant
Roots
Roots help provide support by
anchoring the plant to the ground.
Roots also soak up water and nutrients
that are needed for growth. Sugars and
carbohydrates that the plant uses to
function are stored in the roots. There
are two types of roots, taproot and
fibrous. Taproots are roots with a few
branches that are very thick and
swollen. Carrots are examples of
taproots. Fibrous roots are a bunch of
very fine roots. For example grass has a
fibrous root system.
Stems
Stems carry water and nutrients
from the roots to the leaves. They also
hold up the leaves so that they are
exposed to the sun. The node is where
the leaves join the stem and the
internode is the space between the
leaves and the stem. Food produced by
the leaves travels through the stem. The
cells that do this are called the xylem
and phloem cells. The xylem cells move
the water and the phloem cells move
the food up or down the stem.
Leaves
Leaves are the food factories of
green plants. Leaves are made to catch
light and they have small openings to
allow water and gases to come and go.
Veins carry water and nutrients within
the leaf. A simple leaf consists of a
single leaf blade and a compound leaf
consists of small leaflets. The petiole is
the part that joins the leaf and the main
stem. The cuticle is the waxy coating
that protects the leaf.

The six major
Components of Soil
Flowers
There are six key components to
soil: sand, silt, clay, organic matter,
bonemeal, and peatmoss. The ideal ph
for soil is 7. An ideal soil contains equal
amounts of the components. The
makeup of the soil texture and the
acidity affects the nutrients available to
the plants.
Flowers have a male part and a
female part. The female part is called the
pistil and is located in the middle of the
flower. There are three parts of the
pistil, the stigma, style, and ovary. The
stigma is the sticky bulb that pollen
lands on to start the fertilization
process. The style is the long stalk that
supports the stigma. The ovary is
usually at the base of the flower and
contains seeds that turn into fruit. The
male part is called the stamen and
consists of two parts, the anther and the
filament. The anther produces pollen
and the filament holds the anther up.
Fruit
Fruit is the ripened ovary of the
flower. Seeds are protected by a seed
coat that can be thin or thick. The seed
also contains a short term food supply
called the endosperm. It is used to help
the seed germinate and grow. Seeds are
a plants way of getting from one place
to another.
Photosynthesis and
Transpiration
Photosynthesis is the process by
which plants and some other organisms
capture light energy and use it to make
foods from carbon dioxide and water.
Photosynthesis is when carbon dioxide
and water combine in the presence of
light to produce sugar and oxygen.
Transpiration is the process by which
water vapor is lost through the plants
leaves and other parts. This is a very
important process. Many environmental
factors that affect the rate of
transpiration include light, temperature,
humidity, wind, soil, and water.
