Plant Systems-Biology Flashcards
Dermal Tissue
External-covers the plants entire body which serves as a protective layer
Ground Tissue
Stores water & carbohydrates, assists in transport, and surrounds and supports the conducting tissues
Vascular Tissue
(xylem & phloem)
Conducts Water, Mineral, Nutrients and carbohydrates made by photosynthesis throughout the plant
Plant Organ: Roots
-Hidden organs
-essential for the plants life
-absorbs water and nutrients
-stores food
-thin hair like
Plant Organ: Stems
-support system
-transports water, nutrients and food
-provides a platform
Plant Organ: Leaves
-Food Factories
-Photosynthesis
-Contains stomata for gaseous exchange
Reproductive Structure
Flower
Sepal
Protects the bud
Petals
Attracts pollinators
Stamen
Male
Carpel
Female
Which type of root helps to prevent soil erosion
Fibrous
Which type of root reaches deep for water
Taproot
Cuticle
Prevents water loss
Where does photosynthesis occur?
Chloroplasts
How does water get to the leaf?
Xylem
Xylem
Carries water one way, UP!
-starts at the root hairs
-Water
Phloem
-Starts at leaves
-Goes both ways
-Carries C02 in and 02 Out
-Sugar
Light
Phototropism
Touch
Thigmotropism
Earth
Geotropism/Gravity
Water
Hydrotropism
Petals Function
Intrigues the bees!
Sepal Function
Protects the petals as it develops
Stamen Function
Male Reproductive Organ
Pistil
Female Reproductive Organ
Ovule
Produces egg cells
Pollination from two different flowers=
Cross-pollination
Process when pollen lands on the stigma
Pollination
Process of egg and sperm uniting to form zygote
Fertilization
Pollination of the same flower
Self-Pollination
Seeds Function
Helps make a new plant
Cones Function
Protects the seed
Fruit Function
Protects the seed
