seed part
Seed coat - matured integument, for protection
seed part
Endosperm - reserve food material, rich in starch, oils and proteins
seed part
Embryo - immature plant
part of embryo
Epicotyl - will develop stem and leaves•
Mesocotyl - attachment of the cotyledon
Hypocotyl - will develop part of the lower stem
Radicle - will develop the root
Cotyledon - food storage in dicots, food absorption in monocots
seed germination
Epigeal - most of the seed parts are carried above ground, occurs in dicots

Fruit Types and Layers
Based on the ovary position of the flower
Fruit Types and Layers
Based on the ovary position of the flower
Pericarp - develops from a superior ovary, only the ovary wall thickens
Fruit Types and Layers Based on the ovary position of the flower
Fruitwall - develops from an inferior ovary; the receptacle and ovary wallthickens
Fruitwall - develops from an inferior ovary; the receptacle and ovary wallthickens
False fruit - develops from an inferior ovary; only the receptacle thickens
Based on the type of flower
Simple fruit - develops from a flower with a single pistil
Based on the type of flower
Aggregate fruit - develops from a flower with many pistils e.g. atis and guyabano
Based on the type of flower
Multiple fruit - develops from an inflorescence e.g. jackfruit and pineapple - spike inflorescence
Fruit layers - visible only in fleshy fruits•
Exocarp - external protective layer that changes its color during ripening•
Mesocarp - internal layer which can be fleshy or fibrous•
Endocarp - thin internal layer that surrounds the seeds
fruit -> Seeds are dispersed. Each seed contains a plant embryo. If a seed sprouts, it will become new plant
fruit -> Seeds are dispersed. Each seed contains a plant embryo. If a seed sprouts, it will become new plant -> a mature plant produces a flower. pollination and fertilization takes place -> ovary, each ovule within the ovary contains fertilized egg
Simple Fleshy Fruits
Berry- all the fruit layers (exocarp, mesocarp and endocarp) are soft and fleshy
Simple Fleshy Fruits
·Pepo-with a hard and green exocarp (fruitwall from outer ovary and receptacle!
Simple Fleshy Fruits
·Hesperidium - with leathery exocarp and juicy pulps (placental hairs)
Simple Fleshy Fruits
Drupe-with hard or stony endocarp
Simple Fleshy Fruits
·Balausta -tough pericarp with many seeds
simple fleshy fruits
·Pome-false fruit-fleshy receptacle
Simple Dry Dehiscent Fruits
, Follicle - splits along one side
Simple Dry Dehiscent Fruits
, Legume - splits along two sides
Simple Dry Dehiscent Fruits
,Silique - similar to legumes but with an internal false septum (replum) for seed attachment
