a. XYLEM B. Leaf. C. Flower. D. Stem Which of the following is NOT an example of a plant organ ?
A. CELL. B. Epidermis. C. Roots. D. Leaves The basic structural and functional unit of a plant is?
A. Red oak. B. Azalea. C. Japanese maple. D. DAFFODIL An example of a plant which has herbaceous (ground up)stems is?
A. Carrots. B. LAWN grasses. C. Pine tree. D. Oak tree An example of a plant that has a fibrous root system is?
Flowers can form fruits, while roots, stems and leaves can TRUE
form vegetables
Stomata Transpiration is the loss of water vapor through the
photsynthesis Which term refers to plants making their own food?
All of the above:parenchyma,epidermal, meeristematic In which of the following cells would cellular respiration occur?
Xylem is the primary path for conducting(transporting) Water and nutrients/minerals up from the soil
Dandelions and knock out roses Which of the following is NOT a plant that responds to shorter day length
True Plants make their own food
False In healthy plants, photosynthesis and cellular respiration occur at the same time or
equal rates.
, False All parts of the root tip absorbs water (root hairs)
True Adding mulch to a garden area benefits plants by decreasing water lost to
evaporation
True The best way to distinguish between simple and compound leaves is to look
where the node is located.
False Carbon, nitrogen, iron and copper are examples of MACRO nutrients found in
plants.
False Incomplete flowers are flowers that contain both sexes in the same flower while
complete flowers have separate sexes.
True A tree seals itself instead of healing itself.
True Stomata are holes in the leaf epidermis which are formed by the opening and
closing of guard cells.
List two functions of roots Absorb water , keep plant upright and stable in the ground.
List two functions of stems Support leaves/ flowers ; transport water, food; propagate; store food
List two functions of leaves: Photosynthesis, transpiration, respiration
When plants photosynthesize, they always make more Excess food is stored for later use; this is to ensure the plants survival when
food than is needed at that point in time. Why? photosynthesis is limited or non-existent. Some examples may include night,
extreme cold, extreme heat, etc. Photosynthesis also releases more oxygen than
the plant needs and the excess is available to other organs.
in a stem, the terminal bud is located at the end of the stem; has meristematic tissue; can be dominate over the
auxiliary or lateral bud.
Decreases As the amount of sunlight decreases, the rate of photosynthesis
An example of a fruit that does not have chilling Oranges
requirements
An example of a light that is HIGH in the BLUE range Fluorescent
Photoperiodism refers to the amount of time a plant is Length of nighttime
exposed to a light in order for flowers to bloom
During the process of photosynthesis Food in form of sugar is Made; solar energy is converted into chemical energy.
The correct equation for photosynthesis is? 6CO2 + 6H2O>>>>>>>>>C6/H12/O6 + 6 O2
How does transpiration benefit plants? Cooling of plant tissue and transporting nutrients that are dissolved in the water
