KEY CONCEPT Plants have specialized cells and tissue systems.

Plant tissues are made of three basic cell types. Parenchyma cells are the most common plant cell type. store starch, oils and water help heal wounds to the plant have thin flexible walls

Collenchyma cells provide support to a growing plant. they are strong and flexible. celery strings are strands of collenchyma. they have unevenly thick cell walls.

Sclerenchyma cells are the strongest plant cell type. second cell wall hardened by lignin die when they reach maturity used by humans to make linen and rope makes up the hard or gritty part of a fruit or vegetable

Plant organs are made of three tissue systems. Dermal tissue covers the outside of a plant. protects the plant secretes cuticle of leaves forms outer bark of trees

Ground tissue is found inside a plant. provides support stores materials in roots and stems most commonly made of parenchyma

Vascular tissue transports water, minerals and organic compounds. stem leaf root two networks of hollow tubes xylem transports water and minerals phloem transports photosynthetic products

Which type of cell is found in the hard or gritty parts of fruits and vegetables? Collenchyma Sclerenchyma Parenchyma Plasmodesmata

Plant cells that have thin walls and store starch, oils, and water are Parenchyma Collenchyma Sclerenchyma Vascular cells

Dead parenchyma cells that make up bark form a type of Collenchyma tissue Vascular tissue Dermal tissue Ground tissue

A plant’s ground tissue is found In its outer layer Only in its leaves Above the ground Throughout the plant

Water and dissolved minerals are carried from the roots to the rest of the plant by the Dermal tissue Ground tissue Xylem Phloem
