Cells
Organelles that perform photosynthesis.
What are chloroplasts?
This group of plants is incapable of true secondary growth due to the arrangement of their vascular bundles.
What are monocots?
The region of a stem where leaves or branches attach.
What is a node?
This type of plant tissue is found in roots, stems, and leaves, and is often called “filler tissue”.
What is parechyma?
These tiny, hair-like structures on roots increase surface area for absorption.
What are root hairs?
Two organelles that are found in plant cells but not in animal cells.
What are chloroplasts and cell walls?
Pores on the stem of a woody plant that allow for gas exchange.
What are lenticels?
The region of a stem where new cells are produced for primary growth.
What is the apical meristem?
Botanically, this fruit type is classified as a modified berry with a thick exocarp.
What is a pepo?
This type of root has a single, dominant root.
What is a taproot?
This theory posits that chloroplasts and mitochondria were once free-living prokaryotic cells that were engulfed by a larger cell.
What is endosymbiotic theory?
This tissue, produced inward by the vascular cambium, forms the annual rings of trees.
What is secondary xylem?
An underground, horizontal stem.
What is a rhizome?
This vascular tissue transports sugars and other nutrients from source to sink.
What is phloem?
These are roots that arise from non-root tissues.
What are adventitious roots?
Due to extreme water loss, the cell membrane shrinks and separates from the cell wall.
What is plasmolysis?
Abnormal growth or swelling on a tree's trunk or branches formed by stress, disease, or injury to the tree.
What is a burl?
A mark left on a woody twig where the leaf vascular tissue was attached.
What is a bundle scar?
This layer of tightly packed cells in plant leaves is the primary site of photosynthesis.
What is palisade mesophyll?
These parasitic roots penetrate the host plant's tissues and form connections to its vascular system.
What are haustoria?
The force within a cell that pushes the plasma membrane against the cell wall.
What is turgor pressure?
This structure is made up of cork, phelloderm, and secondary phloem.
What is bark?
A modified stem that is flattened, leaf-like, and photosynthetic.
What is a cladode?
This type of modified root grows upward to access oxygen in waterlogged soils.
What are pneumatophores?
These bacteria form a symbiotic relationship with plant roots in the bean family and facilitate nitrogen fixation?
What are rhizobia?
