28 Analysis: z1.Formation of fruit/seed in a simple fruit OVARY After fertilization the OVARY wall develops 3 layers (endocarp, mesocarp, exocarp) Exocarp Exocarp enlarge become fleshy or dry fruit OVULE OVULE SEED Receptacle Receptacle can be fruit

29 z2. Fruits where seeds are eaten are: Sunflower, beans, peas, peanuts Sunflower, beans, peas, peanuts z3. Distinguish the fruit from other parts of the flower by: Fruit has one or more ovaries with a seed or seeds. Fruit has one or more ovaries with a seed or seeds. z4. An aggregate fruit differs from a multiple fruit by: Aggregate fruit with many ovaries in a single flower Multiple many flowers

30 z5. An aggregate fruit is similar to a multiple fruit by: Both develop specialized tissue in addition to the ovary.
