Topic 7 - Plant Structures and their Functions

• Roots


  Absorb Water and Anchor the plant. Store food ( glucose)
• Stems


  Transport water, minerals, and food ( glucose). Support the leaves and position them so they can receive the most sunlight as possible
• Leaves


  Produce Food ( glucose). Collect sunlight and use it to make food ( glucose). Do the process of photosynthesis
• flowers


  reproduction
• Fruits


  Aid in seed dispersal
• cones


  Reproduction and scales on cones hold seed and aid in seed in dispersal
• tissue


  A bunch of specialized cells working together to perform a specific function
• organs


  Tissues working together form a
• organ system


  Organs working together form a
• organism


  Organ Systems Working together form an
• The organs of a plant including roots, stems, leaves, flowers, fruits, and cones are made out of a bunch of what working together?

  tissues
• List the tissues that work together to form the organs of the roots, stems, leaves, flowers, fruits, and cones.

  Dermal, ground, vascular
• Dermal


  protect leaf and prevent water loss
• Vascular


  transport water minerals and nutrients
• Ground


  photosynthesis and support
• what is found in the dermal tissue?

  Epidermis, cuticle, guard cells, stomata
• What is found in the ground tissue?

  Parenchyma, Collenchyma, Sclerenchyma
• What is found in the vascular tissue?

  Xylem and phloem
• epidermis


  Protect the leaf prevent water loss
• cuticle


  Prevent water cells
• guard cells


  Gas exchange ( CO2 in, O2 out, H2O in and out)- open and close stomata (
• stomata


  Gas exchange ( CO2 in, O2 out, H2O in and out)- opening or pore
• xylem


  Transports water and minerals UP the plant. Water travels from the roots up through the tree to the leaves against gravity.
• phloem


  Transports food ( glucose) down the plant. The leaves make glucose during photosynthesis. The glucose is transported through the phloem down to the roots for storage.
• parenchyma


  Photosynthesis
• collenchyma


  Support in young plants
• sclerenchyma


  Rigid support and protection
• where can the meristematic tissue be found.

  tips of roots and stems
• what kind of cells does the meristematic tissue have?

  Area of actively dividing cells. Undifferentiated cells that are dividing or making more cells (undifferentiated- cells that have no job-stem cells and could become roots, stems, or leaves depending on what jobs they get assigned)
• How does the meristematic help plants grow?

  Helps plants grow taller, longer, and roots deeper in the soil.
• where can the cambium be found?

  Between the xylem and phloem just under the bark
• what kind of cells does the cambium have?


  Area of actively dividing cells. Undifferentiated cells that are dividing or making more cells (undifferentiated- cells that have no job-stem cells and could become roots, stems, or leaves depending on what jobs they get assigned)
• how does the cambium help plants grow?

  Helps plants ( Trees) grow wider
• What is the function of root hairs?

  Increase the surface area and uptake of water
• What is the function of a root cap


  Protects the root meristem and allows for growth of the root. Paves the way for growth of the plant and cell specialization
• what is the male part of the flower and what does it include?

  STAMEN and includes the FILAMENT and the ANTHER
• What is the female part of the flower and what does it include?

  PISTIL and includes the STIGMA, STYLE, and OVARY
• where are eggs found?

  ovary
• Where is the sperm found?

  pollen grains
• Where is the embryo protected?

  seed
